How many gram of NH3 (g) will be required to add in 500 ml, 0.6 N  H2 SO4 to reduce the normality of H2SO4 to 0.1 N.

Answer» As per question the neutralised acid is equivalent to 500ml 0.5N H2SO4.

2NH3 + H2SO4,= (NH4)2SO4

By this balanced equation we get that 1mol H2SO4 requires 2 mol or 34g NH3 for nutralisation.

1000 ml 2N H2SO4 solutiin contains 1mol H2SO4.

So 1000ml 2N H2SO4 requires 34g NH3 for nutralisation.

500ml 0.5N H2SO4 requires

(34×500×0.5)/(1000×2) g NH3

=4.25g NH3.
