FIELD: chemistry.
SUBSTANCE: invention can be used in chemical industry. The method of producing bisulphate and hydrogen chloride solution includes preparing a solution from a chloride, which contains one of bisulphate cations, and a hydrosulphate containing the second one of bisulphate cations, and precipitating bisulphate from the solution. Precipitation is carried out before removing the sulphate cation from the solution while simultaneously obtaining hydrogen chloride solution. The hydrosulphate containing the first of bisulphate cations used is sodium bisulphate, or potassium bisulphate, or ammonium bisulphate, or rubidium bisulphate or caesium bisulphate. The chloride which contains the second one of the bisulphate cations used is magnesium chloride, or aluminium chloride, or nickel chloride, or chromium chloride, or cobalt chloride, or manganese chloride, or copper chloride, or iron chloride, or cadmium chloride, or zinc chloride.
EFFECT: invention enables to simultaneously obtain bisulphates and a diluted solution of commercial-grade hydrochloric acid or an ore leaching solution or a solution for producing gaseous hydrogen chloride.
