Question

A) Calculate the volume of 6 M NaOH required to react completely with the amount of methyl salicylate you used. How much of the 6 M NaOH that you used was in excess of the theoretical amount? B) What volume of 3 M H2SO4 is needed to neutralize all of the disodium salicylate and the excess NaOH present after the initial reaction? How much sulfuric acid was in excess?

Explanation / Answer

From the balanced equation: HOC6H4COOCH3 + NaOH --> HOC6H4COO-Na+ + CH3OH One mole of NaOH is needed for every mole of methyl salcylate, therefore 10 mmole is needed. 6 M NaOH contains 6 moles/L or 6 mmole/mL, then 10 mmole / 6 mmole/mL = 1 2/3 mL
