1. The problem statement, all variables and given/known data The description of the problem is in the given link: http://s906.photobucket.com/albums/ac261/Bashyboy/?action=view¤t=2011-10-11_21-13-53_241.jpg 2. Relevant equations 3. The attempt at a solution Well, I as was able to find the answer to the first problem, which came out to be 51.4 mL of KCl. What I was not able to ascertain was the answer to the second problem. I took the amount of moles contained in the HNO3 and Na2CO3 solutions; I then tried to find the limiting reactant, but I really didn't work. How do I find the answer to the second question. Sorry if any parts of my query are unclear--it is late, and, therefore, I am tired.
