Question

Predict the Normality of H2SO4 if 75 ml of 96.6 % pure H2SO4 added to 425 ml water. The density of H2SO4 is 1.83 g/cm3?

Answer 1

Step-by-step explanation:

Normality is one of the concentration terms.

It is expressed as:

`N=(mass of the substance)/(equivalent mass)* (1)/(volume of solution in L.)`

The volume of the solution is 425 mL.

Mass of sulfuric acid given is:

`mass=volume * purity* density\\ = 75 mL * 0.966 * 1.83 g/mL\\\\=132.5 grams\\`

The equivalent mass of sulfuric acid is 49.0g/equivalents

Hence, the normality of the given solution is:

`N=(132.5g)/(49.0g/equi.) *(1000)/(425mL) \\Normality=6.36N`

Answer is: 6.36N.
