The chemical substance sodium hydrosulfite, commonly known as sodium dithionite or sodium hydrosulfide, has the formula NaHSO2. The compound is the sodium salt of hydrosulfuric acid, consisting of sodium ions bound to two sulphur dioxide molecules. It’s utilised in chemical operations as an oxygen scavenger, as well as in the filtration of drinking water and wastewater.<\/p><\/blockquote>\n

Manufacturing Process:<\/strong><\/p>\n

Sodium hydrosulphite is produced in a two-step process from caustic soda and sodium sulphide. The first step is to produce hypo-sulphuric acid which is a solution of 35% w\/w Sulphuric acid and 65% w\/w water containing all of its oxygen bonded to hydrogen ions. Hydrogen gas is passed through it at 30-40\u00b0C whilst pass through another stream of chlorine into a pool at 22\u00b0C.<\/p>\n
