Question

you have been provided with river water containing nickel sulphate

explain how you will be able to find the concentration of nickel sulphate in the river water.

In simple terms please

Answer 1

The concentration of Nickel Sulfate can be determined through its precipitation in the form of Ni(NH4)2(SO4)2·6H2O as a result of ammonium sulphate addition.
This blue-coloured solid is analogous to Mohr's salt, Fe(NH4)2(SO4)2·6H2O.
