What happens when sodium hydroxide solution is added to ferrous sulphate solution?

What happens when sodium hydroxide solution is added to ferrous sulphate solution?

When ferrous sulfate reacts with sodium hydroxide, dirty green gelatinous ppt. of ferrous hydroxide is formed along with colorless sodium sulfate.

What happens when sodium hydroxide solution is added to ferrous chloride solution?

Answer: When sodium hydroxide is added to ferric chloride solution, a reddish brown precipitate is formed.

What Colour will you observe when sodium hydroxide reacts with iron sulphate?

The nature of the precipitate formed when sodium hydroxide reacts with iron (II) sulphate is of. iron (III) hydroxide which is dirty green in colour and insoluble in excess of NaOH.

What happens when sodium hydroxide is added to iron?

to form a green precipitate. Hint: We know that the green precipitate is of iron (II) hydroxide and the brown precipitate is of iron (III) oxide. Now we have to find out which iron salts react with sodium hydroxide to form iron (II) hydroxide and iron (III) hydroxide.

When sodium hydroxide is added to a solution of ferric chloride write equation for the reaction taking place?

FeCl3 + NaOH = Fe(OH)3 + NaCl Reaction.

What do you see when sodium hydroxide is added in excess to lead nitrate solution?

When an excess of sodium hydroxide is added to lead nitrate, sodium plumbite is formed which gives a colourless solution.

What do you observe when sodium hydroxide solution is added to ferrous nitrate solution?

Answer: When NaOH is added to ferrous ammonium sulphate solution and warmed, both ferrous ion and ammonium ion separate and exhibit their individual properties. A green precipitate of Fe(OH)2 is formed and the smell of NH3 gas from (NH4)+ ion is observed. Hence, it is an example of the formation of a double salt.

What happens when sodium hydroxide reacts with zinc hydroxide?

Bases also react with certain metals, like zinc or aluminum, to produce hydrogen gas. For example, sodium hydroxide reacts with zinc and water to form sodium zincate and hydrogen gas. Zn(s)+2NaOH(aq)+2H2O(l)→Na2Zn(OH)4(aq)+H2(g).

Why does zinc hydroxide dissolved in excess sodium hydroxide?

Zn(OH)2 is amphoteric, so it can reacts with the excess NaOH. Zinc hydroxide will dissolve because the ion is normally surrounded by water ligands; when there is excess sodium hydroxide, the hydroxide ions displace the water ligands and the complex will acquire a −2 charge, making it soluble.

What happens when iron reacts with sodium sulphate solution?

Chemical equation for Iron(III) sulphate (Ferric sulphate), on reaction with sodium hydroxide solutions, gives brown precipitate of iron (III) hydroxide and sodium sulphate solution.

When sodium hydroxide is added to ferric chloride solution a reddish brown precipitate is formed?

We can see here that to balance the Valency of ferric ions three moles of hydroxide ions are needed. The precipitate is reddish brown ( Fe(OH)3 ) in colour. As iron belongs to the transition metal series, it gives colour to its compounds. The precipitate is deposited at the bottom of the container.
