WebOct 18, 2024 · What is the pH of a 0.150 M solution of sodium acetate (NaO2CCH3)? Ka (CH3CO2H) = 1.8 x 10-5. Chemistry 1 Answer 1s2s2p Oct 18, 2024 The pH is roughly 8.96. Explanation: Sodium acetate is the salt of a weak acid and strong base from the equation: C2H 3N aO2 → CH 3COO− +N a+, where: CH 3COO− + H 2O\ ⇌ CH 3COOH +OH − WebAll steps. Final answer. Step 1/3. 10) Na + is a spectator ion in this hydrolysis so, net hydrolysis is given below. C 2 H 3 O 2- + H 2 O ↽ − − ⇀ HC 2 H 3 O 2 + OH -.
