Question

1. True or False: 50 mL of 1M H2SO4 requires 100 mL of 1 M NaOH to completely neutralize it.

2. Give two ways of monitoring pH.

3. 3. True or False: A buffer’s role is to maintain a neutral pH

4. How can solubility be increased? Give TWO ways.

Answer 1

1.True or False: 50 mL of 1M H2SO4 requires 100 mL of 1 M NaOH to completely neutralize it.

H2SO4 + 2NaOH = Na2SO4 + 2H2O

A) True.

3. True or False: A buffer’s role is to maintain a neutral pH.

Buffer role is to maintain the constancy in pH of solution by adding small amount of strong acid/base.

A) False

4. solubility of any substance in solution can be increased by increasing the temperature.

solubility of any substance in solution can be increased by increasing the dilution of the solution.
