Question

.
7) Ferrous Sulphate is mixed with Sodium hydroxide - what type of colour change occurs in this
reaction? And explain the reaction with balanced chemical equation.
(1+2)​

Answer 1

Explanation:

The following reaction can be termed as a double displacement reaction. Here Na(sodium) being highly reactive displaces FeSO4 from its solution. Thus, a dull green precipitate is obtained as follows:

NaOH + FeSO4 => Na2SO4 + Fe(OH)2

Hope this helps :)
