For each of the given solution, the pH of the solution is to be determined from the given concentration of OH − ions and based on the pH value, each solution is to be classified as acidic, basic, or neutral. Concept introduction: The pOH of a given solution is expressed as follows: pOH = − log [ OH − ] The sum of pH and pOH in a solution is always equal to a constant at a constant temperature. At 25 ° C , the sum is equal to 14.00 and it can be shown mathematically as pH + pOH = 14 .0 The pH scale is used to classify the solution as follows: The solution having pH value less than 7 is acidic. The solution having pH value greater than 7 is basic. If the solution has pH equal to 7, then it is neutral.

Question

Chapter 14, Problem 102E

Interpretation Introduction

Interpretation:

For each of the given solution, the $pH$ of the solution is to be determined from the given concentration of $OH−$ ions and based on the $pH$ value, each solution is to be classified as acidic, basic, or neutral.

Concept introduction:

The $pOH$ of a given solution is expressed as follows:

$pOH=−log[OH−]$

The sum of $pH$ and $pOH$ in a solution is always equal to a constant at a constant temperature. At $25 °C$ , the sum is equal to 14.00 and it can be shown mathematically as

$pH+pOH=14.0$

The $pH$ scale is used to classify the solution as follows:

The solution having pH value less than 7 is acidic.

The solution having pH value greater than 7 is basic.

If the solution has pH equal to 7, then it is neutral.
