Chapter 15, Problem 15.72SP

Interpretation Introduction

Interpretation:

The $\text{pH}\text{7}$ buffer system should be chosen from the given set of options.

Concept introduction:

Buffer solution:

An equal concentrations of conjugate acid-base pair in a solution is known as buffer solution and it has constant $\text{pH}$.

pH:

$\text{pH}$ is a logarithmic expression to express a solution is acidic, basic or neutral.  The $\text{pH}$ scale has values between 1 and 14 and on which 7 is neutral, below 7 values are more acidic in nature and above 7 values are more basic in nature.

$\text{pH}\text{=}{\text{-log}}_{\text{10}}{\text{[H}}^{\text{+}}\text{]}$ Higher the amount of solute that dissolved into the solution than saturated solution by increasing temperature to give a supersaturated solution.
