Introduction
We look into many aspects of phosphorous Pentachloride, starting from its methods of preparation, going on to its physical properties, chemical reactions and then structure.
Pre-Requisites:
Decomposition, Hydrolysis, Sublimation, Equatorial, Axial, Tetrahedral, Octahedral.
Activity:
The batteries that we use in practically half of the appliances we use, from the TV remote to the clock? Their electrolytes contain phosphorous Pentachloride as an indispensible component.
Real Life Question:
What is the main component in a chlorination agent? What do battery electrolytes contain?
