Q.

State your observation with chemical equation :

Aqueous solution of ferrous sulphate is treated with sodium hydroxide

Q. What is observed when ferrous sulphate reacts with sodium hydroxide solution?

Q. (a) Explain, with example, how the physical states of the reactants and products can be shown in a chemical equation.
(b) Balance the following equation and add state symbols:
$\mathrm{Zn}+\mathrm{HCl}\underset{}{\to }{\mathrm{ZnCl}}_2+{\mathrm{H}}_2$
(c) Convey the following information in the form of a balanced chemical equation:
"An aqueous solution of ferrous sulphate reacts with an aqueous solution of sodium hydroxide to form a precipitate of ferrous hydroxide and sodium sulphate remains in solution."
