CH3COOH --> CH3COO- + H+
when NAOH is added to this equilibrium systm , OH- will react with
H+ to form
water
OH-(aq) + H+(aq) --> H2O (l)
b)
This will reduce concentration of H+ in the solution and
equilibrium will get
disturbed .In order to attain equilibrium again , the system will
speed
up forward reaction .
Thus addition of NaOH will decrease concentration of H+ , [H+]
Increase concentration of CH3COO- , [CH3COO-]
Decrease concentration of CH3COOH , [CH3COOH]
