Chapter 10: Q. 10.38 (page 346)

If you know the $[{OH}^{-}]$ , how can you determine the pH of a solution?

Short Answer

Expert verified

The pH of a solution is determined as $p H = - \log [H_{3} O^{+}]$

Step by step solution

Introduction

The objective is to determine the pH of a solution when $[{OH}^{-}]$ is known.

Explanation

We'll start by calculating the $H_{3} O^{+}$ using $K_{ω}$ (Ionic product) for water i.e localid="1653974998099" $K_{ω} = [H_{3}^{+} O] \times [{OH}^{-}]$ and $[H_{3} O^{+}] = \frac{K_{ω}}{[{OH}^{-}]} = \frac{1.0 \times 10^{- 14}}{[{OH}^{-}]}$

Then enter the calculate value $[H_{3} O^{+}]$ far computation based on formula $pH$ , which is

localid="1653975011962" $pH = - \log [H_{3} O^{+}]$

As a result, pH can be determined
