Three acids,HCl, H2SO4 and H3PO4 are all 6M in concentration. what are their normalities
Technically this question cannot be answered without equations because the normality depends upon the number of H ions replaced; however, in lower level courses, we often say that the equivalent weight is the molecular weight (molar mass) divided by the number of replaceable H ions. In this regard,
N = M x #replaceable H ions.
For HCl that is 6M x 1 = 6N
For H2SO4 that is 6M x 2 = 12N
