Description
Ammonium chloride without anti-caking agents is a white, odorless, crystalline salt. With no added anti-caking agents, the product remains pure, making it ideal for Applications where additives are undesirable. It is soluble in water and at solution forms a slightly acidic pH. The product has a salty taste and sublimates at heating (passes directly from solid to gas).
