About This Product
Potassium metal shows why alkali metals need protected storage. It is opened only in a controlled area cleared of water, acids, oxidisers, alcohols and ignition sources, by staff wearing splash goggles, gloves and a flame-resistant lab coat, and unused metal stays under its protective storage medium. Planning for a metal fire is part of the risk assessment before use. Export supply of the Potassium Metal Reagent Grade can be arranged to laboratories and schools in Afghanistan, Seychelles, Malta, Bosnia and Herzegovina and Trinidad and Tobago.
Frequently Asked Questions
Q1. What happens when potassium metal contacts water?
It reacts violently, producing potassium hydroxide, heat and flammable hydrogen gas. This is why it is handled only with completely dry tools in a controlled area.
