Title: Calculating Equilibrium Constants of Fe3+ and SCN-
Post by: flatworm on April 17, 2020, 02:44:57 PM

I'm working on a chemistry lab, but I'm stuck. We're doing an absorption lab and I'm not sure how to proceed with the calculations. Should I be using RICE tables for this? If so, could someone show me an example of how I'm supposed to do this?

What is the concrete Problem?

"Calculate the equilibrium concentrations for Fe3+ and SCN– for the mixtures in Test tubes 2-5 in Part III."

I'm having a really hard time understanding the lab because it's my first one online and I didn't do the experiment/collect the data myself. I'm not really looking for the answer to be handed to me or anything, I just want some examples so that I can have a better idea of what to do.

The purpose of the lab was to eventually find the equilibrium constant of a reaction - which I can do - but I'm pretty burnt out and not even sure what info to share here to get help.

If you dont provide data's we cannot help.
If you mix iron III and thiocyanate what is the chemical reaction and how the equation of K.
