1) Net ionic equation is
2) pH = - log[H+]
[H+] = 10-2.79 = 0.0016 M
[CH3COO-] = [H+]
3)
= 0.0016 * 0.0016 / 0.10
= 2.56 * 10-5
Percent dissociation =(amount of dissociated acid / total amount of acid)*100
=(0.0016 / 0.10)*100
= 1.6 %
Degree of dissociation increses with dilution because dissociation of acid happens with the help of energy generated when water molecule dissociates so more water molecule means more energy and hence better dissociation of acid.
