When 0.0030 mol of HCI is added to 100 mL of a 0.10 M solution of a weak base, `R_(2)NH`, the solution has a pH of 11.10. What is 1`K_(b)` for the weak base ?

A weak base, BOH is titrated with a strong acid HA. When 10 ml of HA is added, the pH of the solution is 10.2 and when 25 ml is added, the pH of the solution is 9.1. Calculate the volume of acid that would be required to reach equivalence point.

A solution of weak acid HA was titrated with base NaOH. The equivalent point was reached when 40 mL. Of 0.1 M NaOH has been added. Now 20 mL of 0.1 M HCl were added to titrated solution, the pH was found to be 5.0 What will be the pH of the solution obtained by mixing 20 mL of 0.2 M NaOH and 20 mL of 0.2 M HA?
