Determining Equilibrium Constant Lab Question
« on: March 08, 2019, 02:00:26 AM »
Hello all,

So I've just done a lab where we prepare 5 different solutions of Fe3+, SCN-, and NO3. The concentration of SCN- was varied. At the end I calculated what the equilibrium constants are and am working on the post lab content. It asks me an " By what percentage did the initial concentration of SCN⁻ increase from smallest to highest?"

Now I don't know if I'm just being dense, but I have no idea what this means. I've attached my data tables as I'm pretty sure it has something to do with that.

I would be greatly appreciative if anyone could clear this up for me, thanks!

Thanks for letting me know, I'm not sure why that is but I re-posted this topic with the pictures (hopefully) and would appreciate it if you could give it a look!

You better attach images to your post (Additional options below the post edit field) instead of hotlinking to imgur.

oof, the images are attached on my end, I put the imgur link as a backup. I understand why it may not have worked the first time as it was a google photos link, but on my repost I used the link imgur provided specifically for forums. Any ideas as to why this isn't working for me?
