I just read about the KOH string test...it's strange i have not ever heard of it throughout my long years at school!!!
Anyway, i have KOH pellets and dont know exactly how to make the KOH solution and if i can store the made solution in a plastic container. Anyone know?

Make a 3% solution. We store it in a glass dropper bottle.

This is a stupid question, i know, but 3% KOH is 3 grams KOH in 100 mL water?
