Question

The normality if 0.3M phosphoric acid is??

Answer 1

See, here Molarity=0.3 and we know that Normality=Molarity *n.f. where n.f. is n-factor i.e. acidity of base or basicity of acid here acid given is H3PO3 therefore it’s basicity is 2 (since it can donate two OH- ions) as it is clear from it’s structure now, normality=0.3*2=0.6 therefore, Normality = 0.6 N is the answer
