Interpretation Introduction

Interpretation:

The amount of Sodium carbonate has to be calculated.

Concept introduction:

Henderson-Hasselbalch equation:

${\text{pH=pK}}_{\text{a}}\text{+log}\frac{\left[{\text{A}}^{\text{-}}\right]}{\left[\text{HA}\right]}$

${\text{pH=pK}}_{\text{a}}\text{+log}\frac{\left[{\text{CO}}_{\text{3}}^{\text{2-}}\right]}{\left[{\text{HCO}}_{\text{3}}^{\text{-}}\right]}$
