Question

1. Write the equilibrium equations that result when solid NaCH3CO2 (sodium acetate) is dissolved in sufficient water to produce 5.0 mL of 0.5 M NaCH3CO2 solution. 2. How would the addition of 5 drops of 0.1 M HCl affect the equilibrium systems in Question 1? Justify your answer with an explanation. 3. How would the addition of 5 drops of 0.1 M NaOH affect the equilibrium systems in Question 1? Justify your answer with an explanation.

Answer 1

(1) Sodius acetate is a salt of weak acid and strong base.

so, CH₃Co₂ will undergo salt hydrolysis

Act as base

(2) When Hcl is added, it will react with NaOH, and soon as NaOH is consumed reation will shift in forward (right) direction.

(3) If NaOh is added, then it will react with acid ( CH₃COOH) and will shift reaction in the forward direction.

hence, more amount of NaCH₃Co₂ will get consumed.

(3) If NaOh is added, then it will react with acid ( CH₃COOH) and will shift reaction in the forward direction.

hence, more amount of NaCH₃Co₂ will get consumed.
