Lavana Layanikalude pH | How to find pH of Salts | Kerala PSC Chemistry Easy Trick
In this video, we discuss a "Hot Topic" for Kerala PSC Chemistry: pH value of Salt Solutions (Lavana Layanikal). Learn how to identify if a salt is Acidic, Basic, or Neutral using the Strong Acid/Weak Base concept. We solve important Previous Year Questions (PYQs) to help you secure full marks in upcoming exams.
Topics Covered:
How to find the pH of salts like NaCl, NH4Cl, CH3COONa, etc.
Difference between Strong Acids and Weak Acids.
Difference between Strong Bases and Weak Bases.
Reaction logic:
Strong Acid + Strong Base = Neutral Salt (pH equals 7)
Strong Acid + Weak Base = Acidic Salt (pH less than 7)
Weak Acid + Strong Base = Basic Salt (pH greater than 7)
Questions Discussed:
Which salt solution has a pH less than 7?
Which salt solution is Basic (pH above 7)?
Identifying Neutral salts (pH is 7).
