Rosalic ACID TEST - Milk TEST SODA TEST
Take 5 ml of milk in a test tube and add 5 ml alcohol followed by 4-5 drops of rosalic acid. If the colour of milk changes to pinkish red, then it is inferred that the milk is adulterated with sodium carbonate / sodium bicarbonate and hence unfit for human consumption.
This test will be effective only if the neutralizers are present in milk. If the added neutralizers are nullified by the developed acidity, then this test will be negative. In that case, the alkaline condition of the milk for the presence of soda ash has to be estimated.
AURIN p-ROSOLIC ACID is yellowish or deep-red crystals with greenish metallic luster organic compound. AURIN p-ROSOLIC ACID is not water soluble, but fully soluble in alcohol.
