Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

Consider 100ml of buffer solution that is 0.15M NH3 and 0.20M NH4CI. Which of the following is true? (Select all
that apply.)
The pH of the solution is smaller in value than the pka.
Adding 15ml of 0.10M HCI will increase the buffer capacity.
Adding 5.0g of NH4CI will cause the pH to increase.
Adding 10mL of distilled water will have no impact on the pH.
