Ksp and Keq - Approach to questions (1 Viewer)

[Suzanne.A]

Hi all, so I am wondering when I need to use ICE tables for both Ksp and Keq and how to approach the nature of the questions, particularly when I am given values and don't know what to do with them.

I know that an amalgamation of formulae such as C1V1=C2V2 and n=m/MM can be used, but the problem is, I cannot decide when/ if it's even needed.

Probably more specificity is needed, but generally use RICE (or ICE) tables first when you are info dumped - but make sure that all values are in the same units (that's when you use c1v1, m/MM formulae above to achieve that).

Mainly you use ICE when in two cases:
1. Concentration of one initial species, one eq species
2. Initials and K given
