  1. It may very well be possible that you bit the inside of your mouth at night and it subsequently turned into a full-blown cold sore. The mouth is one part of our body that heals relatively fast. Although at times, when something like a cold sore has flared and you are in pain, it may seem like an eternity for it to heal. If the pain is bothering you enough there is a great product that will numb the area and creates a film over it. Just my two cents.
  2. It was white vinegar that was diluted to 5%. The bleach was in a solution, it is something like 3-6%. It was also older bleach so from what I have read the concentration of sodium hypochlorite would have been lower.
  3. In my haste while trying to finish up some laundry I threw some nearly dry dishcloths (that had vinegar on them) into the washer with a little bleach. Awhile later I thought uh oh. Just wondering what everything thinks as how big of a boo-boo I made. Obviously my intent was not to make chlorine gas. Any and all ideas no this are appreciated. Thanks~
  4. I would like to run this one by everyone here. I like using baking soda as a cleaner; it really works pretty darn well as an abrasive for scrubbing. The other day, I bought some new baking soda becaue we were running low and it was on sale. I noticed that on the new packages of Arm & Hammer they are recommending that you throw it out after 30 days...there is the calendar listed and that is all. On the old package of Arm and Hammer it says on the side of the package to throw it out after 3 months, if in the refrigerator. I personally think what it says on the new package is load of merde and simply marketing's way of trying to convince you that you need to buy more of their product. So the question is this then...how long can one expect baking soda to last really? In the refrigerator as well as in the cupboard. Thanks, Jennifer
  5. "The irony about water is 2/3 of the earth is covered with it. We should try to genetically alter food plants so they can use brackish water. There are many plants that can already do this so we need to transfer some genes. This allows us to stretch the water for irrigation and open new farm land. Maybe we can try to genetically alter humans to drink brackish water. This may require a third kidney or something. Implants. Have they ever tried to implant a desalination device in an animal? Salt water drinking cows." Pioneer, Genetically altering food plants to use brackish water is probably not a good solution as the GM plants that are already out there have failed to live up to the promises... http://www.signonsandiego.com/uniontrib/20080618/news_lz1e18gurian.html
  6. Thanks for responding. No, I did not notice residue on the clothing. But I am thinking that it would be a good idea to rewash them though.
  7. I have a question... I used some oxi-clean (main ingredients being sodium carbonate & sodium percarbonate) while doing the laundry. I had put some in with the liquid soap dispenser in a front loading washer. As it turns out...not all of the oxi-clean and soap was completely washed out of the dispenser and I determined that the washer feeds the water through the same compartment when it rinses. Sooo, I ended up throwing laundry that probably had some of this residue on it into my dryer because I did not know this occurred until I started a new load in the washer. What do you guys think...should this be of concern?? Thanks
  8. Dom3mo, May I ask why are trying to make sodium hydroxide? It is indeed very caustic stuff and if you did not have a very good use for it, I would recommend (imo) that you DONT fool around with it. Jen
  9. Insane_alien, I guess I just think of the caustic drain cleaners first and not the acid ones.
  10. Hello, http://www.thecloroxcompany.com/products/msds/liquidplumr/liquid-plumr.pdf http://www.thecloroxcompany.com/products/msds/liquidplumr/professionalstrengthliquidplumrgel0106.pdf http://www.thecloroxcompany.com/products/msds/liquidplumr/professionalstrengthliquidplumrclogremoverremover.pdf Liquid Plumber products do not have sulfuric acid in them...the "featured ingredient" in them is NaOH. So, if you were to try to use that product your balloon filling experiment would not work.
  11. Greetings and Salutations Everyone, I am new(ish) here. I joined this group because I am interested in science and hope to learn more and be part of some interesting discussions. I meant to introduce myself before, but I never got around to it, so here I am...finally-better late than never, no?
  12. I was just looking for peoples' opinions on it that know more about this stuff than I do. What can I say, considering it started out as NaOH which is nasty stuff it would be natural to be a bit worried about exactly what one may be dealing in any residue that could have been left behind...just freaked out a bit.
  13. Ah, so there is a difference in yield between an inorganic and organic reactions... I have learned something. So, now I have one last inquiry. Does anyone think that the residue (probably mostly sodium carbonate by now as I gather) that would be left on the basement floor poses any harm if you were to come in contact with it?
  14. According to what I found in my last post it seems that there still a possibility that that the sodium hydroxide may not have reacted? Am I correct in thinking this...or am I incorrect? Anyone?? Thanks, Jen
  15. There is one thing that I missed I have stumbled across that I would not have taken into account. The ideal or theoretical yield of a chemical reaction would be 100%, a value that is impossible to achieve in a practical setting. According to Vogel's Textbook of Practical Organic Chemistry, yields around 100% are called quantitative, yields above about 90% are called excellent, yields above about 80% very good, yields above about 70% are called good, yields below about 50% are called fair, yields below about 40% are called poor.[1] Yields may appear to be above 100% when products are impure. Purification steps always lower the yield and the reported yields usually refer to the yield of the final purified product. (this I borrowed from another source)
  16. So, I have this straight. The reaction of sodium hydroide with the carbon dioxide in the air would be 100%-in the end there would be only sodium carbonate. And the sodium carbonate can potentially absorb the carbon dioxide and you will get bicarbonate of soda. So what was once very corrosive and harmful does break down into things that are less harmful. This is good to have this clarified.
  17. Oh okay, YT2095. Back to it being on the concrete floor though... Would it be at all possible that the sodium carbonate would react with the calcium hydroxide in the concrete thus forming sodium hydroxide again? Or would this be a stretch?
  18. What about equilibrium...isn't there the possibility that even exposed to the atmosphere some of the sodium hydroxide stay as is or would it all react becoming sodium carbonate?
  19. So basically...(no pun intended)...there would be sodium carbonate.
  20. If the sodium hydroxide was on a concrete floor...would it make a difference as to it forming carbonate...would there be something else there as well from it reacting with the floor components?
  21. more that likely yes, 6 months would be quite sufficient I would imagine if it had a reasonable surface area and humidity level. there are Plenty of other factors that could make an Exception to this sure, but on the whole, you can more or less say there will be a Very significant amount of the carbonate present And what factors would make this an exception? Just wondering... Jennifer
  22. Suspense is killing you...never meant to hurt anyone with my post... In any case, cleaning out the pipes ended up being a bit of a mess because there was quite a bit of stuff in the pipe.
