Question

when iron (ll) sulphate is treated with sodium hydroxide solution, the colour of precipite is​

Answer 1

Answer:

Iron(ll) ions Fe 2+

react with sodium hydroxide to form green coloured precipitates of iron(ll) hydroxide.

Fe 2+ +2OH − →Fe(OH) 2 (s)

Answer 2

When iron (II ) sulphate is treated with sodium hydroxide you will get a colourless solution of Na2So4 and a green precipitate of Fe(OH)2

FeSo4 + NaOH------- Fe(OH)2 + Na2So4

(green precipitate) (colorless)

Balancing equation:--

FeSo4 + 2NaOH-------Fe (OH)2 + Na2So4
