Answer:
The pKa of ethanol is higher than the pKa of water.
Step-by-step explanation:
The Question above asked us to determine or Predict the relative pKa values of benzoic acid in water and in 95% ethanol.
So, there is going to be a higher pKa recorded for the ethanol than the pKa of water.
The reason is because the ka value will be larger for benzoic acid in water(that is the benzoic acid will act more as an acid here) and there will be less value for ka in 95% ethanol( that is the benzoic acid will act as less acid here than in water).
