What is the final pH of a solution formed by mixing equal volumes of two separate solutions of pH 2.0 and 4.0?
How can we approach the question?
pH refers to the power of hydrogen.
Hint #1: It is not 3.0!
Hint #2: The concept involved is ionic equilibrium.
Hint #3: Find the total concentration of hydrogen ions before applying the formula pH = – lg [H+]
