AP MCQ 08ABCDEFGHIJ PART 1

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

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

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]?

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?

During the titration of a weak acid with a strong base, it is found that 22.0 mL of base is required for complete neutralization of the acid. When the titration is repeated, what can be said when the volume of base added is 11.0 mL?

Which of the following salts will produce an acidic solution?

How many liters of water must be added to 1.00 liter of a strong monoprotic acid to raise the pH by 1.00 unit?

When equal volumes of the following solutions are mixed, which results in a buffer solution?

In order to make a buffer with a pH of 7.40, which of the following acids would be most effective, and what would be the corresponding conjugate base?

H₃PO₄, pKa = 2.15
H₂PO₄^-, pKa = 7.20
HPO₄^2-, pKa = 12.3
