    R.B. Chavan, in Handbook of Textile and Industrial Dyeing, 2011 16.5.1 Vat dyes. Vat dyes are applied by using sodium hydrosulphite (sodium dithionate) as reducing agent and sodium hydroxide as an alkali. Some by-products of sodium hydrosulphite are acidic in nature, necessitating overdosing of sodium hydroxide over stoichiometric requirement. A few of the by-products formed are sulphur
