1. The problem statement, all variables and given/known data I need to know how to do the following. If I have 1L of water with a pH of 7 and I add 1mL Vinegar with a pH of 2.4, what will the pH of the solution then be? I now need to get the pH of the solution back to 7 by adding ammonia which has a pH of 11.6. How much of that do I need to add? I dont need a solution to the problem, i just need to know the equations so that i can solve this problem.
