MAKING POTASSIUM NITRATE FROM CALCIUM NITRATE AND POTASSIUM CHLORIDE

This gallery contains 12 photos.

Disclaimer:  This information has purely educational and scientific intend. Often Potassium nitrate is not available or is too expensive so I decided to describe an economically viable way of synthesizing KNO3 from cheap and available resources.  The process is not difficult, requires no specialized chemicals and the yield is excellent. Oversimplified description would be: Calcium […]

MAKING PLATINUM FOIL AND PLATINUM-TITANIUM ANODES FOR PERCHLORATES / PERSULPHATES
