To calculate the pH of a 0.1 M Na₂CO₃ solution, we will follow these steps: ### Step 1: Understand the Hydrolysis of CO₃²⁻ Na₂CO₃ is a salt that dissociates in water to give Na⁺ and CO₃²⁻ ions. The carbonate ion (CO₃²⁻) can hydrolyze in water to form bicarbonate (HCO₃⁻) and hydroxide ions (OH⁻): \[ \text{CO}_3^{2-} + \text{H}_2\text{O} \rightleftharpoons \text{HCO}_3^{-} + \text{OH}^- \] ### Step 2: Determine the Equilibrium Constant for Hydrolysis ...
