Chapter 14, Problem 14.70SP

Interpretation Introduction

Interpretation:

Grams of $\text{CaO}$ that should be dissolved in sufficient water to make $\text{1}\text{.00}\text{L}$ of solution having $\text{pH}$$10.50$ has to be calculated.

Concept Information:

$\text{pH}$ is an logarithmic expression to express a solution is acidic, basic or neutral.  $\text{pH}$ scale lies values between 1-14 and on which 7 is neutral, below 7 values are more acidic in nature and above 7 values are more basic in nature.

$\text{pH + pOH= 14}$

$\text{pH = -log}\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$

$\left[{\text{H}}^{+}\right]{\text{= antilog(-pH) =10}}^{\text{-pH}}$

$\left[{\text{OH}}^{-}\right]{\text{= antilog(-pOH) =10}}^{\text{-pOH}}$
