Help with iodine and thiocyanate residues

Pharmaboy - 15-5-2020 at 07:52

I am thinking of recreating the iodine clock experiment as NileRed did on his channel and wondering if at the end of the experiment the products obtained can be discharged down the drain, I found in a chemistry experiment book ("Una Química Divertida" , by Miguel Fernandez Braña; I'm afraid it is only in Spanish) that those can be removed by draining iodine residues if you previously make them react with sodium thiocyanate, so I thought that my product mixture obtained in the iodine clock could be eliminated. So I seek the opinion of people with more chemical knowledge and experience than me, since I am only a pharmacy student and I am starting with "homemade" chemical experiments.
Thanks you in advance.
PS: I was wondering if is it necessary to add glacial acetic acid to the reaction? Because according to several sources that I have consulted, some researchers say that it has to be in an acid medium while others that it must not.
