For each of the following solutions, the mass of solute taken is indicated, as well as the total volume of solution prepared. Calculate the normality of each solution.
a. l5.0 g of HCl; 500mL
b. 49.0 g of H2SO4: 250. mL
c. 10.0 g of H3PO4: 100. mL
(a)
Interpretation:
The normality of the given solution is to be calculated.
Concept Introduction:
The normality of a solution is defined as the gram equivalent weight of a solute dissolved in one liter of the solution. The normality of solution is given as:
Where,
The mass of
The volume of the
The molar mass of
The dissociation reaction of
The number of
Hence the equivalence factor of
The equivalent mass of a substance is given as:
Where,
Substitute the value of
