Chapter 11.6, Problem 11.47QAP

Interpretation Introduction

Interpretation: “The solution with a $pH$ of $3$ is $10$ times more acidic than a solution with $pH=4$” should be explained.

Concept Introduction:

► $pH$ of a solution is defined as the negative logarithm of the hydrogen ion concentration of the aqueous solution.

Thus, $pH=-\log \left[H^{+}\right]$

$\left[H^{+}\right]={10}^{-pH}$

Thus $pH$ is numerically equal to the negative power to which $10$ must be raised in order to make it equal to the molar concentration of $H^{+}$ in the solution
