3. What is an ester?

4. Why is sulfuric acid added to the esterification reaction?

Expert Solution

Ans: 4)

Esterification is a relatively slow process at room temperature and does not proceed to completion.

Concentrated sulfuric acid is used as a catalyst, and has a dual role:

Speeds up the reaction and acts as a dehydrating agent, forcing the equilibrium to the right and resulting in a greater yield of ester.

Many different ways have been proposed to make batteries. One cell is set up with copper and lead electrodes in contact with CuSO4(aq) and Pb(NO3)2 (aq), respectively. If the Pb2+ and Cu2+ concentrations are each 1.0 M, what is the overall cell potential? Pb2+ + 2e- ---> Pb E = -0.22 V Cu2+ + 2e- ----> Cu E = +0.34 V answer: 0.56 V. how?
