Want some advice on how to calculate the pH of a solution of sulfuric acid.
What I wish to do is to have 5 different samples of sulfuric acid with 5 different pH each one. I want to know how much water or other chemicals I should add to the sulfuric acid to reach a specific pH. For instance, I want to reach a pH of 5.6, what process should I follow? My chemistry teacher gave me a procedure but I think she is wrong because she is not taking into account the water being added. I just want to double-check. Any advice would be largely appreciated
