WebSO2 is used in the manufacture of sodium bisulphate (NaHSO3) which is used as preservatives for jams, jellies and squashes. Web22 aug. 2024 · The melting point of sulphur is approximately 115.21° C, and its boiling point is approximately 444.6° C. The sulphur molecule polymerizes when it is present between the boiling and melting temperatures, resulting in lower density but higher viscosity. Depolymerization occurs at higher temperatures, resulting in decreased viscosity.
