Aluminium Potassium Sulphate

In the USA, UAE, Iran Iraq, Kuwait, Saudi Arabia and other oil producing areas, several hundred chemical compounds are used in hydraulic fracturing also called fracking, fracing or frac. In some areas like UK only ‘Non-Hazardous’ chemicals are permitted for fracturing fluids by the Environment Agency. All chemicals have to be declared publicly and increasingly, food additive based chemicals are available to allow fracking to take place safely.

Aluminium Potassium Sulphate BP
AlK(SO4)2,12H2O__474.4__7784-24-9

DEFINITION
Content
99.0 per cent to 100.5 per cent of AlK(SO4)2,12H2O.

CHARACTERS
Appearance
Granular powder or colourless, transparent, crystalline masses.
Solubility
Freely soluble in water, very soluble in boiling water, soluble in glycerol, practically insoluble in ethanol (96 per cent).

IDENTIFICATION
A. Solution S (see Tests) gives the reactions of sulphates.
B. Solution S gives the reaction of aluminium.
C. Shake 10 ml of solution S with 0.5 g of sodium bicarbonate R and filter. The filtrate gives reaction (a) of potassium.

TESTS
Solution S
Dissolve 2.5 g in water R and dilute to 50 ml with the same solvent.
Appearance of solution
Solution S is clear and colourless.
pH: 3.0 to 3.5.
