If the acid to base ratio in a buffer increases by a factor of 10,the pH of the buffer

Question

Quizplus · Accepted Answer

The pH of a buffer depends on the ratio of the concentration of the acid component to the base component. When the acid to base ratio increases by a factor of 10, it means that the concentration of the acid has increased 10 times more than the base. This will shift the equilibrium towards the acidic side, resulting in a decrease in pH. Specifically, the pH will decrease by 1 unit (as the pH scale is logarithmic). Therefore, the correct answer is B.
