• Description: Now more commonly known as calcium hydrogensulfite, Ca(HS03)2 is a compound known only in solution. The colorless aqueous solution smells like sulfur dioxide and is made by dissolving calcium sulfite in aqueous S02 solution, or by passing S02 through calcium hydroxide suspensions. Used in large amounts to make cellulose by the sulfite process, it is also used to disinfect barns, as an antiseptic in medicine, and as a preservative.
• Uses: As germicide, preservative, and disinfectant; for washing (1:1000) casks in brewing to prevent souring and cloudiness of beer and to prevent secondary fermentation; as antichlor in bleaching fabrics; largely in manufacture of sulfite cellulose from wood for paper-making.
