Which of the following relationships equating Normality (N) and Molarity (M) for the specified subst — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Normality = Molarity $\times$ n-factor. For $H_3PO_4$, the maximum basicity (n-factor) is 3, so 1 M $H_3PO_4$ = 3 N $H_3PO_4$, not 1/3 N. For $Al_2(SO_4)_3$, total cationic charge is 6, so $n=6$, making 1 M = 6 N and 0.5 M = 3 N correct.
