Ammonium benzoate is incredibly soluble in water. Its solubility increases with temperature; at 20°C, 53 grams of ammonium benzoate could be dissolved in a hundred grams of water. Higher temperatures can increase this value even more. This property of ammonium benzoate makes it useful in tasteful preservation where it can be dissolved in the product to stop microbial growth. Its solubility also affects its application in electroplating baths, where proper dissolution ensures effective pH buffering action.
