Question

You are given three solutions: HCl (Solution A); NaOH (Solution B); pH = 8.76 solution (Solution S). You are asked
to prepare the following solutions, starting with Solution S, and adding small amounts of Solution A or Solution B
to it.


a. A solution of pH = 7.00
To Solution S, carefully add small amounts of Solution A / Solution B (Circle one) till the required pH is
reached.


b. A solution of pH = 6.54
To Solution S, carefully add small amounts of Solution A / Solution B (Circle one) till the required pH is
reached.


c. A solution of pH = 9.87
To Solution S, carefully add small amounts of Solution A / Solution B (Circle one) till the required pH is
reached.
