0.45 g acid of molecular weight 90 was neutralise by 20 mL of 0.5 N KOH. The basicity of acid is
Options
(a) 2
(b) 4
(c) 1
(d) 3
Correct Answer:
2
Explanation:
Gram equivalent of acid = gram equivalent of KOH (0.45 / E)= 20 x 0.5 / 1000
So, E=45
Equivalent weight= Molecular weight / Basicity
So, Basicity=90/45=2
