ICE Box vs just solving

Postby Fdonovan 3D » Wed Jan 22, 2020 8:13 pm

How do we know when we have to use the Ice box versus when we can just use the given concentrations and K value to find the concentrations of missing molecules.

Use the ICE box for when the problem asks for something like the pH or pOH of a weak acid/base and you have to find the concentration of the H3O+/OH-. Or, when the problem asks for the equilibrium compositions of the reaction. Then you'd have to find the concentrations for the reactants using the ICE box

You would need to use an ice box if you are given initial concentrations and/or asked to find concentrations at equilibrium. You can just solve if the concentrations you are given are equilibrium concentrations.
