how pure KI is needed for I2 standardiz. with As2O3
« on: September 21, 2014, 10:45:09 PM »
I am getting low on KI which I use when I standardize 0.1N I2 solution with As2O3. I found out that KI has to be low in Iodates, but was wondering if there is anything else that could interfere ?
Thanks for any inputs, Covek11.
