How do I determine the concentration of 2 separate acids in a solution of water if I know the overall pH of the solution?There exists both formic acid and acetic acid in a 1 liter solution of water. The overall solution pH is stated as 4.0 and it is also assumed that the 2 acids contribute equally to the pH. How do I then determine the molar concentration and quantity of each acid in the 1 liter solution of water?
