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 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.
Consider a buffer solution that consists of two separate components: the weak acid ch3coo aq), and its conjugate base, ch3coo (aq) (added as NaCH3COO
A) which component will react with H+ from a strong acid? write the ionic equationvfor the reaction that occurs when H+ is added to the buffered solution.
B) which component will react with oh- from a strong base? Write thebionic equation for the reaction that occurs when oh- is added to the buffered solution.
(b) Barbituric acid, HC.HN.O, (aq), is a weak acid with a Ka of 9.8 x 10 Calculate the [H+], pH
