The compound that is added in the solution to increase the ionization of formic acid should be identified Concept introduction: The strength of an acid refers to its degree of ionization. The acid that ionizes completely is termed as a strong acid whereas the acid that undergoes partial ionization is a weak acid. HCl and HNO 3 are strong acids while CH 3 COOH , HF and H 3 PO 4 are weak acids. According to the Le Chatelier’s principle, when a system in its dynamic equilibrium is subjected to the change in concentration, temperature, volume or pressure, it will adjust to diminish the changes made to it. The equilibrium shifts in the opposite direction so as to offset the change.

Concept introduction:
The strength of an acid refers to its degree of ionization. The acid that ionizes completely is termed as a strong acid whereas the acid that undergoes partial ionization is a weak acid. HCl and HNO3 are strong acids while CH3COOH, HF and H3PO4 are weak acids.
According to the Le Chatelier’s principle, when a system in its dynamic equilibrium is subjected to the change in concentration, temperature, volume or pressure, it will adjust to diminish the changes made to it. The equilibrium shifts in the opposite direction so as to offset the change.
What volume of 0.500 M HNO2 should be added to 500 mL of 0.750 M KNO2, so that the pH of the resulting buffer is 3.23 .
A buffer is made by adding 0.300 mol CH3COOH and 0.300 mol CH3COONa to enough water to make 1.000 L of solution. ThepH of the buffer is 4.74. (a) Calculate the pH of this solution after 5.0 mL of 4.0 M NaOH(aq) solutionis added. (b) For comparison, calculate the pH of a solution made by adding 5.0 mL of 4.0 M NaOH(aq) solution to 1.000 L ofpure water.
(8): Calculate the pH and percent protonation of 0.10 M ammonia NH3 (aq)(use Table 15.9 to find the Kb of this weak base)
