Re: ice chart
You will use an ICE chart when given the initial concentration of something (especially a weak acid). You then use the ICE chart to find the concentrations at equilibrium--- these concentrations are used to solve for K.
Re: ice chart
Typically the problems provide initial molarity or ask for you to calculate the molarity or initial values. I is for initial molarity, C is for change, and E is for equilibrium concentration

Re: ice chart
For those problems, you are usually given an initial molarity/partial pressure and are asked to find values relating to the equation being at equilibrium

Re: ice chart
I think the main reason for using an ice chart would be that you are given a weak acid. If you are given a strong acid, there is no need to use one because we can assume that the acid completely dissociates. For a weak acid, on the other hand, it only partially dissociates, which is where an ice chart comes in handy.

Re: ice chart
Technically you could solve a problem without using an ice chart, it's just an easier way to organize and understand the information you are given.

Re: ice chart
ICE charts are useful when working with weak acids which only partially dissociate in solution.
