Question

10) In procedure B you are performing an acid-base titration and the reaction you are looking at is: H+ + OH- H2O.

By performing this acid-base titration, you will be able to learn about the total amount of H+ in solution. It is important to understand the differences between the amounts of ascorbic and citric acids and the total amount of H+ in solution. Here is an example to help you understand.

Consider the two following solutions:

Solution 1 is prepared by dissolving 1.0 mol of ascorbic acid and 1.0 mol of citric acid in 1.0 L of water.

Solution 2 is prepared by dissolving 2.5 mol of ascorbic acid and 0.50 mol of citric acid in 1.0 L of water. Which of the following statement(s) is (are) correct when both of these solutions are titrated with the same NaOH solution?

Select all that apply.

A) Although solutions 1 and 2 contain different quantities of ascorbic and citric acids, they will both require the same amount of NaOH solution to reach the equivalence point.

B)Overall, 3.0 mol of OH- ions will be needed to titrate solution 2.

C)Overall, 4.0 mol of OH- ions will be needed to titrate solution 1.

D)Overall, 4.0 mol of OH- ions will be needed to titrate solution 2.

E)The total amount of NaOH solution required to reach the equilvalence point for solutions 1 and 2 cannot be the same as the number of moles of each acid is different.

F)Overall, 2.0 mol of OH- ions will be needed to titrate solution 1.
