ThoSieber Posted April 19, 2012 Posted April 19, 2012 So I need a bit of help. I know when you neutralize an acid, you use a base, and that it creates a salt and H2O. But I only know this in the most general way possible, as my teacher has done one example of this. I don't blame him, I just want practice. So, I have to neutralize H2SO4 with NH4OH. How do I figure out what salt is formed?
mississippichem Posted April 19, 2012 Posted April 19, 2012 The acid donates a proton to the base. Which of those species is a proton donor? Keep in mind that an ammonium ion can't be protonated again. Consider sulfuric acid and ammonia instead. If sulfuric acid protonated ammonia it would make an ammonium ion and leave behind a hydrogen-sulfate anion. The "ammonium hydroxide" you have written there is really just what happens when you dissolve the weak base ammonia in the weak acid water. It's the same concept.

mississippichem Posted April 23, 2012 Posted April 23, 2012 no this acid do not react. i did it before! Sulfuric acid reacts fine. What do you mean?
