Potassium is the seventh most abundant element on earth. It is one of the most reactive and electropositive of all metals and rapidly oxidizes. Webattention is required if potassium chromate is split on skin or eyes. The area on which the chemical is split must be washed with plenty of cold water for 15 minutes. If it split on clothing e.g. lab coat, it must be immediately removed. If any spillage occurs, inform the teacher in charge of the lab. lampen traktor
