Introduction
•
It can be defined as a shift in equilibrium on adding
a substance that provides more of an ionic species already present in the
dissociation equilibrium.
•
Common ion effect is based on Le Chatelier’s
principle.
Pre-Requisites:
Reaction, ionization,
water, acid, base, le chateliers principle
Activity:
Some foods are acidic in nature some are basic
Real Life Question:
What is the use of an
acid..?
