Re: 100g/Litre I2
Weigh the liquid, then divide the total weight in grams by 100. divide 100 grams by this number, and you will have your percent.

Re: 100g/Litre I2
It is generally accepted when exact calculations are not critical (as in this case), that grams are equivalent to milliliters (considering its an aqueous solution or sg close to 1.000). If you have 100g. in 1000ml., then you have approximately a 10% solution.

Re: 100g/Litre I2
Seems about right,
we got 46g of I2 out of 500ml of 10% I2/KI/IPA vet iodine solution.
And the stuff's 4ukp for 500ml OTC unwatched.
Fantastic.

Re: 100g/Litre I2
Thanks.
What I ment was how to extract. swim said he just can't get it to go. Filters nothing..
But no worries with extreamly expensive tinc otc pharm 2%.(~$11-$12 US.50mL).Shit.

You can find some extraction methods on the rhodium site in the chem section.
