• Question 01:

What is the pH of a 0.001 M solution of a strong, monoprotic acid?

• Question 02:

When making a buffer of pH = 5, acids with the following Ka values are available. Which would be the best acid to use?

• Question 03:

For a buffer with a pH = 4.87, that contains a weak acid that has an equilibrium constant Ka = 1.0 x 10-5, what can be said of the ratio of [salt]:[acid]?

• Question 04:

1.0 L of a buffer solution with a pH value = 5.92, that contains a weak acid with a pKa of 5.12 is diluted by adding water to make the new total volume 2.0 L. What is the new pH of the buffer solution?

• Question 05:
