**Question:**What is the pH of a 0.680 M solution of Ca(NO₂)₂ (Ka of HNO₂ is 4.5 × 10⁻⁴)?**Explanation:**This question involves calculating the pH of a solution containing calcium nitrite, which is a salt derived from a weak acid (HNO₂) and a strong base (Ca(OH)₂). The dissociation constant (Ka) is provided to understand the extent to which the weak acid dissociates in solution, which will help determine the pH.**Key Concepts to Understand:**1. **pH Calculation:** This involves using the concentration of the solution and the dissociation constant to find the concentration of hydrogen ions, and then using this to calculate the pH.2. **Hydrolysis of Salts:** Ca(NO₂)₂ will undergo hydrolysis in water, and the nitrite ion (NO₂⁻) will react with water to produce OH⁻, making the solution basic.3. **Equilibrium Expressions:** Setting up an equilibrium expression using the known values and solving for the unknowns.This question requires knowledge of chemical equilibrium and acid-base reactions to approach the solution methodically.
