Is Sodium Benzoate soluble in HCl NaHCO3 and NaOH

31-5-2010Is Sodium Benzoate soluble in HCl NaHCO3 and NaOH? As for HCl I'm guessing benzoic acid is formed along with NaCl so I guess sodium benzoate is soluble in HCl? I honestly don't even know how to approach this Thanks for the help in advance

Question: NaC7H5O2 (Sodium benzoate) : chemistry

Benzoic acid needs 400 C to decarboxylate under acid or base catalysis-it doesnt do it this way at room temperature In soft drinks etc it is a radical mechanism initiated by vitamin C and traces of metals which produce a hydroxy radical This then pulls the hydrogen of benzoic acid giving a benzoate radical which loses CO2
