Question

What is the normality of a 0.015 m solution of phosphoric acid assuming complete dissociation? a. 0.015 n b. 0.030 n c. 0.045 n d. 0.060 n

Answer 1

The normality of phosphoric acid at complete dissociation is 0.045 N.

First, let us differentiate molarity and normality. In terms of units, molarity is in moles/L while normality is the number of gram equivalents/ L. In addition, normality can be a multiple of molarity, which in the case of acid-base reactions is dependent on the available H+ or -OH ions neutralized or donated.

Phosphoric acid, with the chemical formula of H3PO4, can donate 3 H+ ions when completely dissociated. In this case, we can say that the number of equivalents is 3.

Normality = 3* molarity

Normality = 3* 0.015 m

Normality = 0.045 n
