(3 points) The acetate ion (CH3COO-) is a weak base. Write down the base-ionization equation for CH3COO- in water. b) (2 points) Complete the expression for the base-ionization constant (Kb) for CH3COO-. c) (5 points) Calculate the pH of a 0.40 M solution of CH3COO- (Ka for CH3COOH = 1.8 x 10-5).
Correspondingly, is ch3coo an acid or a base?
Acetic acid (CH3COOH) is a weak acid. In water it loses its acidic hydrogen to the water molecule as H+ ion. The acetate ion (CH3COO-) thus formed is the conjugate base of acetic acid. Since it is a strong base, the above equilibrium is overwhelmingly shifted to the left.
