Chapter 19.5, Problem 51LC

Interpretation Introduction

Interpretation : The buffer system maintains the pH of a solution is to be related and effected.

Concept Introduction : A buffer is a solution that retains the pH of a solution irrespective of the addition of small amounts of acids or bases.

Answer to Problem 51LC

The buffer system maintains the pH of a solution because it is made up of weak acid or weak base along with its salt.

Explanation of Solution

The equilibrium law, commonly known as Le Chatelier's principles, is used to forecast how certain changes will affect a system in chemical equilibrium (that is the change in pressure or temperature).

A weak acid and one of its salts or a weak base and one of its salts are solutions that are used as buffers.

Buffers are formed by the combination of weak acids or bases with their respective salts.

The pH of the buffer is maintained at a particular value irrespective of the addition of hydrogen ions and hydroxide ions.

The buffer system is compared to Le Chatelier’s principle where the system is in equilibrium, the change occurs when the equilibrium is affected due to the surroundings.
