Using ICE table
I understand how to set up the calculations for ICE tables, but I'm confused when I can detect that I will have to use it in a problem. Correct me if I am wrong, but I can assume that I will use it when I am given a, for example, Ka value + molar concentration?
Re: Using ICE table
You can set up an ICE table for problems where you're given initial/final molar concentrations and an equilibrium value or pH in the question. I'm pretty sure we'll be using ICE tables for a lot, if not all of the equilibrium questions on the midterm.

Re: Using ICE table
ICE tables should be used when you are given either starting or ending conditions and need to find the other. An equilibrium constant (Ka/Kb) is also needed to do the calculations.

Re: Using ICE table
Based on the practice questions, I would say usually you can clue in on if you need to use an ICE table if there is an unknown concentration of H30+ ions or OH- ions you have to calculate. The questions could ask for pH or pOH and to get those, these concentrations would be needed. Ka and a molar concentration is essentially used to find these concentrations using an ICE table.

We are always trying to solve for the equilibrium. Unless stated, you assume the amount of mol/liters is initial, not equilibrium.

Re: Using ICE table
ICE Tables can be used when you're given the initial or final concentrations and when the reaction is at equilibrium

Re: Using ICE table
ICE Tables are useful in so many circumstances. Finding initial concentrations, final concentrations, pH and pOH (from H3O+ and OH- concentrations respectively), and for finding Ka and Kb. Oftentimes I just start with an ICE table right off the bat because it also helps me organize the information, and more often than not, it's the key to solving the problem as well.

Re: Using ICE table
ICE tables can be used whenever chemical equilibrium is part of a problem. For instance, if we're given initial concentrations and need to find equilibrium concentrations, or vice versa, ICE tables would be most helpful. If given Ka and a molar concentration, we could find any other concentrations and use those to find pH or initial concentrations.
