Acetic Acidic
Acetic acid (CH3COOH) is a weak acid that reacts with water to form the acetate ion (CH3COO-). Write out the balanced reaction, and identify the acid, base, conjugate acid, and conjugate base.
The equilibrium constant, K, for the above reaction is 1.8x10-5. If you add 1.31 g of acetic acid (FW=60.5 g/mol) to 24.2 mL of water, what are the equilibrium concentrations of acetic acid and acetate? What is the pH?
The acetate ion is the conjugate base of acetic acid (CH3COOH), which is a weak acid with a pKa=4.74. Write out the balanced reaction when sodium acetate dissolves in water, and identify the acid, base, conjugate acid, and conjugate base. What is the equilibrium constant for this reaction?
If you add 1.72 g of sodium acetate (FW=82.0 g/mol) to 28.7 mL of water, what are the equilibrium concentrations of acetic acid and acetate? What is the pH?
