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

10.0 mL of the strong acid has been added. The value of Kb for H2NNH2 is 3.0 x 10-6.
