NeonBlack Posted December 15, 2005 Share Posted December 15, 2005 The other day, I was making a solution of water, 10% sds and 10 M NaOH. When I addedthe sds to the water first and then the NaOH second, Almost immediately, there was a white precipitation. When I added the NaOH first and then the sds, nothing happened. Why does this happen one way and not the other, and what is the precipitant? Link to comment Share on other sites More sharing options...

RyanJ Posted December 15, 2005 Share Posted December 15, 2005 What is sds? Explaining that may help others in solving your problem Standard solution seems the most obvious bet but I can't really think of anything else that fits it Cheers, Ryan Jones Link to comment Share on other sites More sharing options...
jdurg Posted December 15, 2005 Share Posted December 15, 2005 Sodium Dodecyl Sulfate may be another possibility, especially if he's into soap making. Link to comment Share on other sites More sharing options...
Yggdrasil Posted December 15, 2005 Share Posted December 15, 2005 It is probably sodium dodecyl sulfate (lauryl sulfate). It is a common surfactant used in biochemistry and molecular biology experiments. Link to comment Share on other sites More sharing options...
YT2095 Posted December 15, 2005 Share Posted December 15, 2005 my 1`st guess would have been local heating as the soln conc will be stonger one way than the other (like the acid to water thing). although I would have thought it should eventualy reach an equilibrium over time no matter HOW its mixed.

NeonBlack Posted December 16, 2005 Author Share Posted December 16, 2005 Yes, sodium dodecyl sulfate is it. Sorry for being unclear. Link to comment Share on other sites More sharing options...
