Multiple Choice. Suppose you have 1 liter of an aqueous solution with a pH of 7 that is called solution A. Your lab partner adds 500 milliliters of another aqueous solution that has a pH of 2 that is called solution B to solution A (solution A originally had a pH of 7 before solution B was added to it). What will the resulting pH of the final solution be after the 500 milliliters of solution B are added to 1 liter of solution A to make the final solution that contains a total of 1.5 liters of liquid?
