Answer 2

Heya Mate ur answer is..

(i) When a ferrous salt solution is treated with a solution of sodium hydroxide, a greenish precipitate of ferrous hydroxide is obtained.

FeSO + 2NaOH → Fe(OH) + Na SO

When a ferric salt solution is treated with a solution of sodium hydroxide, a brown precipitate of ferric hydroxide is produced.

Fe (SO ) + 6NaOH → 2Fe(OH) + 3Na SO

(ii) The ferrous salts are generally green-coloured, whereas the ferric salts are brown in colour.
