ice chart

In a question, how are we able to tell when to use and 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.

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

[Rosha Mamita 2H]

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

[Amy Lefley 1J]

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.

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.

[Brian Chang 2H]

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

[Tony Chung 2I]

when they give you the initial value of a weak acid.
