So I graduated last year with a chemical degree and I started working in a lab. I'm still pretty nervous about making mistakes, so when I had to prepare a tricky experimental setup, I wrote down what I wanted to do and sent it to a colleague for him to check. He's just a bit older than me, but seems much more confident. I can't really tell what he thinks of me, and the tone of his answer is not helping (copied it below). Do you think he's happy with me?

Not sure about that formula (You can simplify the solubility = that complicated expression line. In your case that expression is basically something $\times$ zero).
For your experimental part. I would have used 10^2 instead of 10^1 mg of zinc but ok.
One thing though: ensure quantity of water - quantity of potassium > quantity of iodine.
Otherwise there is no point.

Hint 1

Only very specific parts of the text are useful for this riddle.

Hint 2

The text layout is important. Not sure this works on a phone screen. Edited the layout to hopefully make it clearer.

    $\begingroup$ Note 2 : If this question fails to fly here, I think I can move it verbatim to the Workspace for it to thrive $\endgroup$

  • $\begingroup$ Is the inclusion of the things that aren't chemicals here intentional (e.g. soda and iode)? $\endgroup$

  • $\begingroup$ Nah, that's just me being and a non-native speaker who relied a bit too much on linguee. I'll edit it to make it a bit more realistic. $\endgroup$
