4. How could you tell which of the solutions that were able to buffer well against added acid has the greatest buffering capacity against acid?

a. Add equal amounts of acid to each solution until the pH of one solution changes significantly.
b. Add equal amounts of base to each solution until the pH of one solution changes significantly.
c. The solution with the highest pH after adding the 2 ml of acid has the greatest buffering capacity.

Step 1

Buffer solution & Buffer capacity:

An aqueous solution consisting mixture of weak base and its conjugate acid or weak acid and its conjugate base.  Its pH value changes very small when a small amount of strong base or an acid added to it.

A quantitative measure of the resistance of a buffer solution to pH value change on the addition of hydrogen ion or hydroxide ion is known as buffer capacity.

Step 2

Slowly add equal amounts of acid to each of the solutions and see how much the pH value changes with each addition of acid for each solution.  The solution which has the least amount of change in pH value is the best buffer solution and has the highest buffering capacity.
