THe aqueous Iodine
solution I mentioned before is Lugol's.
Lugol's is 5% I2 and 10% KI, or in that proportion with more water, but in the UK it's likely to be 5% I2 if it's called Lugol's
solution is just the BP name for 5% Lugol's. It is the same stuff. The price from Asset chemist isn't expensive. That's a lot of Lugol's
for the money
