Chapter 9.5, Problem 12PPC

Interpretation Introduction

Interpretation:

The hydronium ion concentrations of given solutions are should be found.

Concept introduction:

$\text{pH}$:

The Negative logarithm of base $\text{10}$ Hydrogen ion concentration is known as $\text{pH}\text{.}$

$\text{pH}\text{=}{\text{-log}}_{\text{10}}{\text{[H}}^{\text{+}}\text{]}$

From the above equation Hydrogen ion concentration is,

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

• The exponent of $-pH$ gives of hydrogen ion concentration.
• Acidity of a solution is normally given by $\text{pH}$ in chemistry and it gives information about the concentration of hydrogen ion in solution and it is,
• $\text{pH}$ of the acid solutions are $\text{pH}\text{=}\text{0-7}$ and basic solutions are $\text{pH}\text{=}7\text{-14}$ so 7 is a neutral range and water is having $\text{pH}\text{=}7$
