Hi all, I'm looking for a simple way to know when the liquid within a tank that we store waste chemicals in is at a certain level, so that we know when to empty it. Has anyone used anything simple for this? Thanks for your help!!

Is there any relation between density of a solution and the solute in a solution?may be like Raoult law.

Hello, What does remove a solvent under high vacuum means?Does that means under reduce pressure? Do i need a vacuum pump? thanks

Hi all Context: I have fit some data to a function using excel solver to minimise the error squares (sum of squares method). Question: How I do I determine an appropriate error given experimental error as well as goodness of fit? I know i can calculate an error due to the goodness of fit directly from the sum of squares: σ2 = ∑(yexperimental - f(x))/(N - 1) so: ycalculated = f(x) ± σ But if my experimental data has an error (for example, reading temperature off a thermometer with an error of ±0.05, such that each value of yexperimental has an error of 0.05) how do I account for this error in σ (if necessary)? I will be using these values in further ca…

Anyone know any simple way of extracting alkoids from organic material

Anyone here have any experience setting up and/or operating an ICP-MS?

Hi all. At some point a car coolant received a dosage of some aluminium powder 'supposed' to do some good. Which way would you suggest to backwash the radiator in order to remove any obstruction caused by such powder ? Would detergent, or borax, a solvent, or gasoline or something else work better without harming the aluminium cored radiator which is healthy but assumed semiobstructed ?

Can anyone see a way to remove nitrates, amines, chloramines from pool water contaminated with calcium hypochlorite as the sanitizer or monopersulfate as an oxidizing agent. I can see removal of proteins through use of a protein skimmer, maybe but what is left behind? Perhaps nitrogen fixing for formation of atomic nitrogen that would evaporate off...Okay it's a stretch. What about in conjunction with a chlorine generator? Love to hear your thoughts unless this is the stupidist idea you have ever heard. Best Goober

I am looking for a standalone metal container, about 1 foot tall and 1/2 foot at the base for the purpose of melting LiNO3 and KNO3. It should have a heating element and should be able to reach 600°C. Does anyone know where I can find one online?

Hi, I can precipitate gold dissolved in aqua regia if the gold is just pure.I use sodium metabisulfite.However,if I dissolve the gold from ore in aqua regia,I cannot precipitate the gold.What's wrong?Might other metals or mud in the soil spoil it?Does anything prevent precipitating?Any help will be highly appreciated.Thanks a lot in advance.

Are there any amino acids that can be synthesized at home in a practical way? I have ammonia, phenylethylamine, and phenibut, if that helps. I'd prefer to synthesize l-tyrosine or l-glutamine, but any is good for me.

This is my first post at this forum, I looked around the forum and found so many people being helped out by others; so I feel optimistic about posting my request here. I'm from Pakistan (ahem) and a Chemical Engineer. I wish to develop my own lab at my home, or use a small hall for a workshop for my chemical business which I am yet to begin. Could you recommend a few chemicals that are easy to make and profitable? If you could give me a link to resources on the internet or give me titles of book perhaps that would be very helpful too. There are very few people in Pakistan making chemicals other the regular dishwashers, cleaners, etc. Please recommend a few ch…

Today I asked my professor if we could perform the experiement when you submerge a copper penny in nitric acid. He said that he would consider doing it if I provided an etching. I don't possess that much knowledge on etchings, but could someone explain to me what they are and what the best ones would be for such an experiment and if at all possible the least expensive? Thanks in advance!

I want to protect my bismuth oxide layer to preserve the color over time, but clear coats seem to disrupt the wave interferences. What should I try? Thanks, Ernie

Hi Everyone, I'm obviously not a chemistry or science major but I don't know where else to turn for an informed answer. I'm working on a new recipe and I need to predict the scoville rating. I'm using several different types of peppers to get the best flavor but some of them are just extremely hot and need to be diluted. Here's my data. How do I calculate it? Thanks, JB

With all the clean water crises affecting so much of the world, you start to wonder if there are ways to actually create water for some these people using various chemical reactions. There are many reactions that yield water and other products which are not too difficult to filter out and not terribly harmful to the environment. Why can't we utilize these reactions for purposes of water genesis? I always wondered. What do you think of this?

This post is about an apartment I moved into in April. I guess the most obvious threats come from ingesting pant chips, inhaling dust stirred up by a sanding tool or licking the surface (if you're a child), but couldn't you also get considerable amounts of lead into your system by constantly inhaling air that came into contact with (was blown across and in between) peeling lead paint? For example, air that came through a window which had lead paint peeling off the exterior frame? This is my room window: As you can see, there are some pretty nasty lead paint peels coming off. There is also a black/grayish residue on the exterior sill, which I'm gue…

Hello .... I have a pure nickel and i need to creat a solution to ele ctoplating ... I need to know how to make nickel salt ... Please help me ...

I've been doing some extensive research on electrolysis and working out the proper setup to get some very old car parts cleaned safely, easily, and effectively. One of things I don't want to do is to create a poisionous Hexavalent Chromium solution so I will be avoiding using stainless steel as my anode. I saw people recommending not using Galvanized Steel either, but only because if it is used as the container for the solution and the anode at the same time, you would have a major leak on your hands in a matter of hours. My plan, is to use a 55 US Gallon plastic drum as the main container, then use a galvanized steel 31 US Gallon garbage can as the anode inside …

Hi I'm working as an electrician doing installation on ships etc. When we're testing generators we use a thub with sea water in it and 3 copper tubes connected to the three-phase 230v system. We're gradually lowering the tubes into the water which results in a increase of current flowing. No problem to pull 300++ amps. My question is, are there any chemical reaction happening when applying 3phase AC current to sea water like that, or will the water just boil?

Okay so i am taking big interest in chemistry now. Mainly because it goes with physics and astronomy. I plan on doing lots of background research and scouring through equipment but i want to scale this up and build a nuclear fusor for research, learning and pure fun. Not to mention how big a thing it will add to my resume. I ask for other peoples help and knowledge as i go through this project. This will take A LOT of background research in order to successfully complete this feat. I am sure that in the process i will learn a lot about chemistry, physics and quantom physics in the process and its well worth it all. Thank you for any future knowledge and advice. Kagen…

I electrolysed a brine solution using graphite electrodes. No attempt was made to minimize the chlorine (produced) reacting with the electrolytic solution. After a few hours, a white sludge (possibly Mg(OH)2 and Ca(OH)2) was formed, as expected. This was removed and the electrolysis was continued. After a few hours, the graphite cathode started to flake off. The anode remained intact. This is surprising since I don't think hydrogen reacts with carbon under these experimental conditions. I initially thought maybe the Chlorate ion formed due to the dissolution of chlorine in the solution reacted with the graphite cathode, but that doesn't explain the fact that the ano…

I'm looking for suggestions on acetic anhydride productions at home. Maybe a way of making a home made ketene lamp? I don't have an extensive knowledge of chemistry and this makes the most sense to me.

Space A question from someone else on Ask.com that I've wondered about.... If vast areas of outer space contain nothing, does that mean those areas contains no atoms either? Best Answer - Chosen by Asker The "vacuum of space" refers to the relative lack of material in space. The Earth's atmosphere doesn't really stop at a certain place and then "space" begins. The air gets thinner as you go up from the surface and the farther from Earth (or the Sun) you get the thinner it is. It gets thinner still if you leave our solar system and even thinner in intergalactic space. But it is always there. In reality, no volume of space can ever be perfectly empty. A perfe…
