Sodium Bisulfite can be prepared by bubbling sulphur dioxide in a solution of sodium carbonate. 38 percent of solution is produced by neutralizing sulphur dioxide gas with sodium hydroxide. Sodium Bisulphite in contact with chlorine bleach will release harmful fumes.
Sodium Bisulfite is used in almost all commercial wines, to prevent oxidation and to preserve flavor. It is also used in the analysis of methylation status of cytosine in DNA.
Sodium Bisulfite is primarily used for water treatment to remove excess chlorine in drinking water. It is used to bleach pulp in the pulp and paper industries.
