. A buffered solution is one that resists a change in _________ when either a strong acid or a strong base is added to it.
Interpretation:
A buffer solution should be explained.
Concept Introduction:
A buffer solution is formed from weak acid or base and its conjugate base or acid respectively. It can be acidic or basic depending on the weak acid or base taken. For example: Buffer solution formed by acetic acid and acetate ion is an acidic buffer and buffer solution formed by ammonium hydroxide and ammonium ion is a basic buffer.
According to Le Chatelier’s principle, to any change in the chemical reaction at equilibrium, the reaction will shift to the direction to overcome that change.
In variety of chemical processes, buffer solution is used to keep the pH of solution constant.
The principle behind this can be explained as follows:
The dissociation of a weak acid is represented as follows:
To this solution, if a strong acid is added at equilibrium, according to Le Chatelier’s principle, the equilibrium will shift to left
