1. The problem statement, all variables and given/known data This was part of a lab i preformed to determine rate law for HCl and Mg. 50 mL of 0.5M, 1M, 1.5M and 2M HCl solutions were made using water and this was used with Mg ribbon to find the rate law. The same 0.5M, 1M, 1.5M, 2M HCl solutions were made in 100mL solution that contained water. I was told that the 100mL solution of HCl diluted in water provided more accurate results, than the 50mL solution of HCl dilluted in water. I was wondering why this is the case? 2. Relevant equations 3. The attempt at a solution Don't have that great an idea, but the increased volume of solution provides more surface area for reaction, therefore greater results?
