1. How many moles of benzoic acid are present? Determine how many moles of sodium bicarbonate are contained in 1 mL of a 10 % aqueous solution? (A 10 % solution has 1 gram of solute in 9 mL of solvent.) Is the amount of sodium bicarbonate sufficient to react with all of the benzoic acid?
2. To isolate the benzoic acid from the bicarbonate solution, it is acidified with concentrated hydrochloric acid. The concentration of hydrochloric acid is expressed in various ways on the inside back cover of this laboratory manual. What volume of acid is needed to neutralize the bicarbonate?
