A-Level Chemistry: Finding the final pH of a solution

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...
