										Moles of NaOH added to the mixture =  0.1 X 0.2 =  0.02 molesCH3COOH is a weak acid and does not completely dissociate in aqueous solution.Ionization reaction  CH3COOH + H2O  ---->    CH3COO-  +  H3+OAcid dissociation constant, Ka = [CH3COO-] [H3+O] / [CH3COOH]  (1)The initial and equilibrium constant for the reactants and products is  CH3COOH   CH3COO-  H3+OInitial  0.2M   0  0Assuming x moles are dissociated at equilibriumEquilibrium  0.2-x or 0.2  x  xAs acetic acid is a weak acid with a degree of dissociation of less than 5%,  value of x
