Chapter 16, Problem 16.30QP

Interpretation Introduction

Interpretation: The $\text{pH}$ of the given solution at $\text{25}{}^{\text{o}}\text{C}$ has to be calculated

Concept Information:

$\text{pH}$ definition:

The concentration of hydrogen ion is measured using $\text{pH}$ scale. The acidity of aqueous solution is expressed by $\text{pH}$ scale.

The $\text{pH}$ of a solution is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration.

$\text{pH}\text{=}{\text{-log[H}}^{\text{+}}\text{]}$

Molarity:

Molarity is defined as the ratio of number of moles of solute to the number of litres of solution. The concentration of solute in solution is measured using a concentration unit called molarity.

The unit of molarity is moles per litre.

The equation for molarity can be given as,

$\text{Molarity (M)}\text{= }\frac{numberofmolesofsolute}{litresofsolution}$

To Calculate: The $\text{pH}$ of  the given solution at $\text{25}{}^{\text{o}}\text{C}$
