Question

calculate the normality of o.45 g of barium hydrogen in 125 ml solution in reactions that replace both hydroxide ions

Answer 1

The molar weight of barium hydrogen phosphate (BaHO₄P) is 233.31 g/mol.

The normality is

$$N=m/(\Mu V)\cdot2=0.45/(233.31\cdot0.125)\cdot2=\\ =0.0309\text{ N}.$$
