Inorganic Chemistry

i was reading my organic book the other day and i came across the haloform reaction, which intrigued me. for those not familiar, it involves the oxidation of a methyl ketone by a hypohalite to a carboxylic acid, liberating chloroform. in short: R-C(O)CH3+3NaOCl---->R-C(O)CCl3+3NaOH----->R-COO- + Na+ + HCCl3 i was wondering if anyone knew of specific conditions for this reaction to occur under, the expected yield and perhaps some other notes that should be made concerning this reaction. also, since acetone is a ketone with two methyl groups coming off from the carbonyl group, does anybody not think that one could do the following? H3C-C(O)CH3+NaOCl-…

In a beaker of solution, Each sulphuric acid almost completely ionizes to give two H+ ion when the solution is not at a high concentration. What I want to ask is, if the concentration of a salt in a solution is very high while the concentration of sulphuric acid is very low, what will the ionization go? Completely or just give one H+ per molecule?

How could i make plaster of paris out of calcium sulfate (and no they arent exactly the same)? When i put calcium sulfate in water and dry its not hard at all. I heard you have to make it into gypsum or something.

If i was to make nitric acid via the sulfuric acid- potassium nitrate method, how would i accurately figure out the concentration of the nitric acid knowing the amount of liquid the NO2 will dissovle in,the amount of H2so4 and its conc., and knowing amount of potassium nitrate, and assuming all the gas will dissolve? also, just making sure: the colder the water the better the gas will dissolve in it, correct?

Heres the story. I was bored so i put ammonia and sulfuric acid into test tube hoping some ammonium sulfate would be made. A day later i took that mix and pored it in a steel pan i ususally dry my chems in. After a day in the pan i looked and WOW! it turned greenish blue, and had brownish grayish little liooked like turning things in there. The bottom of the pan was nice and clean, compared to the sides which were maore grey- the bottom turned lighter gray. The orange color on the base of the pan disappeared but was left on the sides (the color form heating iron oxide in it). im not sure what the reaction was. Does anyone know? heres pics of what the pan looked like:

Can anybody give me basic instructions with limited materials available at a household to make Potassium Nitrate ? (KNO3)

For a long time, I've had this idea in my head, but never really got around to verifying whether it would work or not. If this works, it would be a perfect way to create Plutonium for you element collectors out there. Unless you're scared (or smart ) You would need: Americium or Radium (Legality Questionable) U238 (Legal) Beryllium (Legal) Borated Parrafin (Legal) Lead (Legal) Let's say you had a 1'x1' lead block and you drilled 2 holes 3"x3" right next to each other, and you drilled a small drillbit-sized hole connecting the two holes. You put Americium or Radium in Hole #1, along with beryllium coated in borated parrafin, line the lead with aluminum f…

I am attempting to disolve a 45 pound zinc ingot into water, looking for a 10% zinc solution. I am using DC current to make a colloidal zinc solution and find the process too slow. What could be used/added to speed the process. I am attempting to do the same with copper metal rods. The end products will be used as plant micronutrients. I have available calcium chloride, boron, urea, sulfur, ammonium sulfate, potassium carbonate and vinigar. Would any of these help? Thank You

does anyone know the main impurities in Activated carbon. If so what would be the main one present? I've got an XRD of all the impurities if anyone wants to see it, i'll put it up. cheers

If I were to obtain a small amount of MgO what exciting stuff could I do with it? I have some effectively useless Mg ribbon lying around and I've only ever seen Mg burn once! The product being MgO, what could I do with it? Also will much [math]Mg_3 N_2[/math] form from the Mg reacting with the nitrogen in the air? If so what can I do with it? If not what can I do with the MgO ?

Alright. I go to school at Brooklyn Teachnical High School and a project we have to do is come up with a type of battery. I have done research on Concentration Cells becasue the topic interests me and have come up with a idea for a battery. Instead of using Copper and Copper Sulfate, would it be possible to use Sodium Nitrate and Sodium. The way i think of it. The anode will give up one electron to which frees Na+ ions to increase the concentration of the solution and consequently frees one electron to the cathode per each freed ion. On the cathode side the electrons that have arrived from the anode react in the surface of the electrode with the solutions Na+ ion forming…

can someone give a list of some inert metals? much obliged

I'm doing water electrolysis, i have got the appartus from the lab. I used electric adapter converts AC to DC and vise versa...What i realized the procces is too slow like it will take day to seperate hydrogen and oxygen, any reason why? So, i used salt as catalyist and the constant was 20 min. I have done 3 experiments to see the effects on effeciancy on electrolysis: using different rods, temprature of water, and voltage. I wanted to measure the amount of hydrogen that is in tube?? ANYONE KNOWS HOW.. And anyone knows any other reason why the color of water changes other than salt? what i think but im not sure, the rod is also taking reaction not only salt, if t…

I know many pyrotechnic composition's burn rate increase with pressure. Just how is this? i do not understand. What i mean is how does it begin to burn so fast that a "firecracker" vilently explodes. I understand why the case explodes, but am wondering why the Bp begins to burn so fast in it. Is it the particles being pushed together or something. I just cant visualize it.

Hey, just wondering if any of you could give me a hand with some calculations. I was just carrying out the Vanadomolybdate phosphoric acid method for orthophosphate in wastewater. I don't know how to convert mg/L PO4 3- to mg/L P or to mg/L PO4 3- -P. Just wondering if any of you have a quick calculation for converting this...

I just heard that the pope's casket's are wood around Zinc. isn't Zn a good Reduction agent so won't it corrode fast? Thank you

we were asked to think about this question in our class today, and i am not entirely sure the answer its to do with enthalphy heat of reactino stuff The question was something like why in the pracs we did involing the neutralisation acedic acid and HCL, was the change in temperature of the HCL greater? my theory, and the keyword here is theory (or mroe correctly wild assumption ) is that..... that stronger acids dissociate more (i have no real basis for this claim, just remember hearing it somewhere), and so there are more breaking of bonds, thus there must be a greater release of energy, resultingn in the greater increase of Temp. in the HCL neutral…

Hi everyone. As a doped silicon junction generates a current when photons strike, how could a pair of ¿non-miscible? thin liquid compounds be formulated to generate current under sunlight, each with its electrode ? electrode1 -------xxxxxxxxxxxxx floating layer electrode2 -------zzzzzzzzzzzzz sunken layer Miguel

Which of the following reaction is more vigorous? K2O + HCl, Na2O + HCl. I know that the rate of KOH+HCl and NaOH + HCl is more or less the same.

The concept of solid turning into a gas is pretty hard for me to understand. It makes sense when i look at the phase-diagram of CO2, but if i try to picture it in my head its confusing. So after some thinking about Dalton's Law, Charles Law, and PV=nRT, i concluded that the boiling point of CO2 is lower than its melting point. Would that be correct? Does the relatively low pressure of 1 atm automatically cause the molecules to divert far away once the crystalline structure has broken? im asking these questions cause i have a test tomorrow and want to understand everything. Thanks

Hey guys/gals. I have two big reports ahead of me for finals. First, I have to determine the % Sb in a sample of tartar emetic by an iodimetric titration process. Second I have to determine the mass of Cr in an unknown chromate sample by iodometric titration process. If anyone has any good web sites/books/etc that explain the theory behind iodi/iodometric titrations that would be great. Thanks a lot !!

Does anyone know how i could synthesize some potassium carbonate?

Hi. Cannot find how to discern if an unmarked automobile wheel is magnesium or aluminium. Any sure way to test please ? If a drop of battery acid is applied to an alloy rim, what reaction, color, etc. is expected if aluminium or if magnesium ? Or any other simple way to tell ? Thanks, Miguel

FeCl3 (aq) + KBr (aq)--> I'm not sure if this comes out to be FeBr3 (aq) + K+ (aq) + Cl- (aq), or FeBr3 (aq) + K+ (aq) + Cl2 (aq) (I know these aren't balanced; I'll probably do that later). basically, does chloride stay an ion, or does it recombine to form chlorine? this has been bothering me for ages...thanks in advance! (the same deal with FeCl3 + KI...chloride ions, or Cl2 as product? arg!)

Why do they call hydrogen peroxide hydrogen peroxide. Shouldnt it be called hydrogen dioxide. My only guess is that it is called this because there are also two hydrogens. I can see with sulfur dioxide SO2, because there is one sulfur. Two oxygens to one sulfur, hence "sulfur Dioxide". But this means that water would be Hydrogen Dioxide instead of hydrogen oxide. Is there just some type of exception with hydrogen that makes it have these wierd names, or am i just trippin.
