Sour potassium sulfate (potassium bisulfate, potassium hydrogen sulfate) - rhombohedral crystals, density 2.24-2.61 g / cm3. T. pl. 218.6 ° C.
The reagent is readily soluble in water (32.7% at 20 ° C), the reaction of the aqueous solution is acidic (K2SO4 crystallizes from the solutions). At 160-170 ° C, the reagent partially begins to transform into K2SO4.
It is used as a component of a flux in metallurgy, a sulfonating agent in the production of dyes. In analytical chemistry, for the conversion of some compounds into readily soluble forms .
