Potassium Acetate USP
Acetic acid, potassium salt --- [127-08-2].
Potassium Acetate contains not less than 99.0 percent and not more than 100.5 percent of C2H3KO2, calculated on the dried basis.
Identification: A solution (1 in 10) responds to the tests for Potassium and for Acetate.
pH: between 7.5 and 8.5, in a solution (1 in 20).
Loss on drying: Dry it at 150 for 2 hours: it loses not more than 1.0% of its weight.
Heavy metals: the limit is 0.002%.
Limit of sodium: To pass the test not more than 0.03% of sodium is found.
Potassium Acetate BP
C2H3O2K -- 98.14 -- 127-08-2
Potassium acetate contains not less than 99.0 per cent and not more than the equivalent of 101.0 per cent of C2H3KO2, calculated with reference to the dried substance.
A white, crystalline powder or colourless crystals, deliquescent, very soluble in water, freely soluble in alcohol.
A. It gives reaction of acetates.
B. It gives reaction of potassium.
Solution S: Dissolve 10.0 g in distilled water and dilute to 100 ml with the same solvent.
Appearance of solution: Solution S is clear and colourless.
pH: Dissolve 1.0 g in carbon dioxide-free water and dilute to 20 ml with the same solvent. The pH of the solution is 7.5 to 9.0.
Reducing substances: Dilute 10 ml of solution S to 100 ml with water. Add 5 ml of dilute sulphuric acid and 0.5 ml of a 0.32 g/l solution of potassium permanganate. Mix and boil gently for 5 min. The solution remains pink.
Chlorides: Dilute 2.5 ml of solution S to 15 ml with water. The solution complies with the limit test for chlorides (200 ppm).
Sulphates: Dilute 7.5 ml of solution S to 15 ml with distilled water. The solution complies with the limit test for sulphates (200 ppm).
Aluminium: If intended for use in the manufacture of peritoneal dialysis solutions, haemofiltration solutions or hem dialysis solutions, it complies with the test for aluminium. Dissolve 2.0 g in 50 ml of water and add 5 ml of acetate buffer solution pH 6.0. The solution complies with the limit test for aluminium (1 ppm). Use as a reference solution a mixture of 1 ml of aluminium standard solution (2 ppm Al), 5 ml of acetate buffer solution pH 6.0 R and 49 ml of water. To prepare the blank use a mixture of 5 ml of acetate buffer solution pH 6.0 R and 50 ml of water.
Iron: Dilute 5 ml of solution S to 10 ml with water. The solution complies with the limit test for iron (20 ppm).
Heavy metals: Dissolve 5.0 g in water and dilute to 20 ml with the same solvent. 12 ml of the solution complies with limit test A for heavy metals (4 ppm). Prepare the standard using lead standard solution (1 ppm Pb).
Sodium: Not more than 0.5 per cent of Na, determined by atomic emission
Loss on drying: Not more than 3.0 per cent, determined on 1.000 g by drying in an oven at 100 °C to 105C.

A jackal woke up early in the morning and went in to the plains. He looked at his long shadow in the rising morning sun and said to himself, "I must have a camel for my meal today".
He kept moving around till noon and it was getting hot and the jackal was tired. He was also hungry and thirsty. He looked at his small shadow in the mid-day sun. He murmered, "I was only joking about the camel, a mouse will do".
