Chapter 16, Problem 16.23QP

Interpretation Introduction

Interpretation:

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

Concept Information:

$pH$ Definition:

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

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

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

Molarity:

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

The unit of molarity is moles per litre.

The equation for molarity can give as,

$\text{Molarity (M)}\text{= }\frac{\text{number}\text{of}\text{moles}\text{of}\text{solute}}{\text{litres}\text{of}\text{solution}}$
