Potassium picrate is a yellow explosive powder with a bitter taste. It is the potassium salt of picric acid with initial explosive properties like all metal salts of picric acid. It is soluble in acetone and ethanol , it hardly dissolves in cold water, but a yellow coloration can still be seen, in hot water it dissolves only moderately. Under a 2 kg drop hammer, there is a 50% chance that it will explode at a height of 21 cm. It can be produced by neutralizing an aqueous picric acid solution with potassium hydroxide . It is used in pyrotechnics in a mixture with potassium nitrate in crying sentences.
