ICE tables

Postby EMurphy_2L » Mon Jan 20, 2020 5:38 pm

when do we use an ICE table? like what words in a question should signal us to use one?

If you need to find the equilibrium concentration of a reactant of product or need to use the equilibrium concentration in a calculation you generally will need an ICE table. Also if you have to find the pH of the solution given the concentration of reactant, you will also most likely need an ICE table.

If you are dealing with a weak acid or base, you would also use an ICE table because you don't know how much dissociates (versus a strong acid/base that dissociates 100%).

You use an ICE table to observe how concentrations change at equilibrium.

When you are given Ka or Kb, that is another indicator you will be likely using an ICE table because you do not know how much of the reactant will dissociate.

It is normally used to calculate the equilibrium constant K of a reaction. Or when K is given, it can be used to calculate one or more of the concentrations in the table that are unknown.
