Vedclass · Answer

(B) The number of equivalents of acid equals the number of equivalents of base for complete neutralization.$Eqv. 	ext{ of } H_3PO_x = Eqv. 	ext{ of } NaOH$$1 \, mole 	imes 	ext{Basicity} = \frac{	ext{mass}}{	ext{Equivalent mass of } NaOH} = \frac{80 \, g}{40 \, g/mol} = 2 \, Eqv.$Thus,the Basicity of the acid is $2$.For phosphorus oxoacids,$H_3PO_3$ has a basicity of $2$ (where $x = 3$).Therefore,$x = 3$ and the acid is dibasic.
