did I really get 5% Lugol's??

[Guest guest]

Hi all!

I am really excited!

After 2 weeks of asking here and getting help and looking

for where to order on the internet, I suddenly thought I phone the wife of a

friend working at the local drug store.

I asked whether I could buy half a liter of Lugol’s

5%, and she said not that many, because she has not that much kalium iodide in

the store at the moment.

She asked what 5% meant, I guessed it meant 5% of iodide and

iodine measured to the distilled water. She said that’s the double they

usually do, but she can do it…

So I got it here already, it says:

 10’000 gr Iodum (iodine)

 20’000 gr kalii idodidum (kalium iodide)

170’000 gr aqua purificata (distilled water)

I am really bad at arithmetics, but is that not 7, 5%???

Or does the 5% mean sth else?

Can anybody help???

Thanks a lot!
