Calculate the concentration of H3O^+ ion...

Calculate the concentration of `H_3O^+` ions in a mixture of 0.02 M acetic acid and 0.1 M sodium acetate. `K_alpha` for acetic acid is `1.8 xx 10^(-5)`.

Text Solution

AI Generated Solution

To calculate the concentration of \( H_3O^+ \) ions in a mixture of 0.02 M acetic acid and 0.1 M sodium acetate, we can use the Henderson-Hasselbalch equation, which is particularly useful for buffer solutions. ### Step-by-Step Solution: 1. **Identify the Components**: - We have acetic acid (\( CH_3COOH \)) which is a weak acid. - We have sodium acetate (\( CH_3COONa \)) which is the salt of the weak acid and provides the conjugate base (\( CH_3COO^- \)). ...
