Question
![**Problem Statement**: Calculate the pH and the equilibrium concentration of Se²⁻ in a 6.77×10⁻² M hydroselenic acid solution, H₂Se (aq).
**Given Data**:
- \( \text{For } H_2Se, \, K_{a1} = 1.3 \times 10^{-4} \)
- \( K_{a2} = 1.0 \times 10^{-11} \)
**Required**:
1. \(\text{pH} =\) (Calculate the pH of the solution)
2. \([Se^{2-}] =\) M (Calculate the equilibrium concentration of Se²⁻)
**Solution**:
(Steps to show calculations would follow here on an educational website, focusing on acid dissociation constants and equilibrium equations based on the provided data.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9aca1772-1e0c-4e24-86a8-736d39b6760d%2Fc70e8bac-26b0-4f47-97d2-6c069e4bd089%2Fp3p6dqp_processed.jpeg&w=3840&q=75)
