Hi All,
our teachers regularly do an experiment reacting dilute sodium thiosulfate solution with dilute hydrochloric acid.
This produces in the reaction, hydrogen sulfide gas solution which we get returned to the prep room in a waste container.
I know a recommended way of disposing this waste solution is to add iron chloride solution and then a slight excess of solid sodium carbonate.
Can anyone advise me what iron chloride solution (iron 11 or 111), in what concentration and how much?
I would be very grateful,
~Robyn

HI Robyn,
Iron (II) Chloride solution will be the one to use, and the concentration to use would simply be a Staurated Solution. This will see you through with no problems.
Cheers,
