Explanation:

Sulphur reacts with sodium hydroxide in different ways, depending on the reaction conditions.

At very high temperatures (600°C +), the reaction produces sodium sulphate, sodium sulphide and water vapour

4S + 8NaOH ⟶ Na2SO4 + 3Na2S + 4H2O

In boiling solution though (120°C),and with different stoichiometric quantities, sodium sulphite is produced rather than the sulphate

3S + 6NaOH ⟶ Na2SO3 + 2Na2S + 3H2O

Phosphorus reacts with NaOH to produce phosphine gas (toxic!) and sodium hypophosphite

3NaOH + 4P + 3H2O ⟶ PH3 + 3NaH2PO2

The correct substitute is a sodium hydrogen sulphite.

  • Sulfur dioxide reacts with sodium hydroxide solution to form sodium sulphite which further reacts with sulfur dioxide to form sodium hydrogen sulphite.
  •  Also known as a heptahydrate of sodium sulfite.  But it is less effective due to greater susceptibility to oxidation by air.
  • Sodium sulfite has reducing properties.  Sodium sulfite is capable of exhibiting bleaching, desulphurizing and dechlorinating activity.
  • This agent was used by some food industries to help maintain the freshness of food products.
  •  It is an ingredient used in many medicinal applications.  
  • It helps them maintain strength and stability.  
  • It is slightly toxic and dissolves slowly in water.

hydrogen sulphite.

2NaOH+SO2→Na2SO+H2ONa2SO3+H2O+SO2→2NaHSO3.
