Introduction
• Ka is called the dissociation or
ionization constant of acid HX.
• It can be represented alternatively in terms
of molar concentration as follows,
• Ka = [H+][X –]
/ [HX]
Pre-Requisites:
Reaction, ionization, water, acid, base
Activity:
Some foods are acidic in nature some are basic
Real Life Question:
Why is phosphoric
acid an ingredient of cleaning agents, a weak acid..?
Key Words / FlashCards
