Chapter 16.10, Problem 20PPC

Interpretation Introduction

Interpretation:

From the given set of reactions the salts which will affects the $\text{pH}$ has to be identified.

Concept introduction:

pH scale: A scale which is used to express the acidity or basicity of a solution.  The change in concentration of either positively charged species or negatively charged species will affects the $\text{pH}$ of the solution.

$\begin{array}{l}\text{pH}\text{=}\text{-}\text{log}\left(\left[{\text{H}}^{\text{+}}\right]\right);\text{pOH}\text{=}\text{-}\text{log}\left(\left[{\text{OH}}^{\text{-}}\right]\right)\\ \text{pH}\text{=}\text{7}\text{neutral}\text{solution; pH}\text{=}\text{<7}\text{acidic}\text{solution; pH}\text{=}\text{>7}\text{basic}\text{solution}\end{array}$
