Question

When sulphur is heated with NaOH (aq)? The compounds
formed are
(a) Na₂S+H₂O
(b) Na₂SO₃ + H₂O
(c) Na₂S+ Na 2S₂O₃ + H₂O
(d) Na₂S₂O₃ +H₂O

Answer 1

Answer:

option a might be correct

Explanation:

Answer 2

Na₂S+ Na 2S₂O₃ + H₂O are formed.

Explanation:

• When sodium reacts with concentrated sodium hydroxide, there's a reaction.

• The reaction yields black precipitate of sodium sulphide with the formation of water soluble sodium thiosulphate and water.

• The reaction is

• 4S + 6 NaOH = 2 Na₂S+ Na 2S₂O₃ + 3H₂O

• This is a disproportionation reaction which is where sulphur reactant is both oxidised in thiosulphate and reduced to sulphide.

• So both oxidation and reduction of the reactant is seen here.
