Preparing a solution
« on: January 18, 2023, 04:14:27 AM »
I’m new to experimenting in chemistry and preparing solutions

(link to automatic titration of Fe2+/Fe3+ solutions removed)

I am going to do a somewhat similar experiment but I need to prepare a solution of similar amount of that found in the experiment from Iron(III) nitrate and Ammonium iron(II) sulfate. Would taking 0.5 g of each not be correct? Or how should I think?

Hard to tell how you plan to follow the experiment with no other reagents. If it is just to play with the procedure starting with 0.5g of substances you mentioned is about as good starting point as any other.

Sadly the linked procedure didn't say anything about expected ranges of initial concentrations of the ions in the sample, which makes is useless.

Thanks Borek. I will start with 0.5 g of each and try that  :)
