It is reversible

Question 10

Is the bass hydrolysis reversible or not?

Answer 10

It’s not reversible

Question 11

Why do you need to add a lot of water to an acid hydrolysis of an Ester?

Answer 11

Because it’s a reversible reaction therefore a lot of what is needed to push equilibrium to the right
