Properties:
Single crystal is inclined white crytallized powder, a proportion of 1.667, soluble in water, alcohol, insoluble in air
heating oxidation is decomposed into sodium and sulfur dioxide. In pure oxygen in combustion is generating sodium,
method and sulfur.
Application:
Mainly used for photographic industry as fuser agent. Tanning when potessium dichromate salt reductants and
nitrogen exhaust neutralizers, salt, wheat stem and hair bleach and pulp bleaching agent of the emergence of
chlorine when. Also used in tetraethyl lead, dye intermediates such as manufacturing and ore mention silver etc.
