Answer 1

Answer:

The chemical formula of Mohr salt is (NH

)

2

Fe(SO

)

2

.6H

2

O

We are given:

Given mass of Mohr salt = 3.92g

Molar mass of Mohr salt = 392g/mol

Volume of solution = 100mL

Concentration of mohr salt is

volume(L)

mole of mohr salt

=

100/1000

3.92/392

M=0.1M

Now, the chemical equation for the ionization of mohr salt follows:

(NH

)

2

Fe(SO

4

)

2

.6H

2−

+6H

2

O

From the equation,

we can say that the concentration of sulfate ions =(2×0.1)=0.2M
