11.115 (f) equilibrium shift

Postby Golbarg Rahimi 3k » Sun Dec 10, 2017 8:30 am

In the online exercises, adding water is like adding a reactant and makes the equilibrium shift to the right. However in question 11.115, adding water has no effect on the equilibrium. Both equations have the same states. Liquid water and aq product. So how does water affect equilibrium?

Water has no effect on the reaction of aqueous solutions since they are in fact surrounded by water.

Adding water allows us to visually see the protonation or deprotonation of an acid or a base:

Base + H2O <---> OH- + conjugate acid
Acid + H2O <---> H3O+ + conjugate base
