The food preservative sodium benzoate, NaC6H5CO2, is a
salt with a basic anion. (a) If 25.0 g of sodium benzoate is dis-
solved in water to make 150.0 mL of solution, what is the initial
molar concentration (in moles per liter) of the anion? (b) Write
the chemical equation for the proton transfer reaction of the
anion with water. Identify the acid and the base in this reaction.
