Accordingly, how do you dissolve sodium benzoate?
Sodium benzoate is supplied as a white powder or flake. During use it is mixed dry in bulk liquids where it promptly dissolves. Approximately 1.75 oz (50 g) will readily dissolve in 3 fl oz (100 ml) of water. In contrast, benzoic acid has a significantly lower water solubility profile.
Does sodium benzoate dissolve in NaOH?
You can't easily dissolve a solid in a solid. The solubility of benzoic acid in an aqueous NaOH solution is simply the solubility of sodium benzoate in water, a bit over 60 g of sodium benzoate per 100 ml.
