Many students have problem in this fundamental chapter on Acids, Bases & Salts. One of the basic concepts lacking is the determination & differentiation of Strong Acid Vs Weak Acid & Strong Base Vs Weak Base.
First, we need to understand that:
- Acid –> pH < 7
- Pure Water –> pH = 7
- Base/Alkali –> pH > 7
Next, we need to differentiate between Strong vs Weak of Acids/Alkalis using examples. Examples given in the chart below will help you to learn better. Copy & print the chart out and paste it in your note if necessary.
