Identification test
Benzoate test (IT-5) was positive. Or add ferric chloride test solution (TS-101) to 10% of the sample solution, should produce light yellow precipitation. Potassium test (IT-27) was positive. Or dilute hydrochloric acid test solution (TS-117Chemicalbook) acidized 10% sample solution, filtration. Adjust the filtrate to neutral with sodium hydroxide test solution (TS-224), add 1 part (volume) saturated sodium hydrogen tartrate solution and 1 part (volume) ethanol, then shake. There should be white crystalline precipitation.

Stability and storage conditions are edited
Potassium benzoate is stable at room temperature under normal storage conditions and should be kept in an airtight container due to its slight hygroscopic properties. Exposure to high humidity and high temperatures should be avoided.
