I can see the questions. The first question (Unit 1, Q1) is: "Explain all the theories of acid and bases in details." - but that's a 10-mark question. You asked for a 2-mark answer in easy language. Here it is:

Q1. Explain all the theories of acids and bases. (2 Marks)

1. Arrhenius Theory

  • Acid = gives H⁺ (proton) in water. Example: HCl → H⁺ + Cl⁻
  • Base = gives OH⁻ in water. Example: NaOH → Na⁺ + OH⁻

2. Bronsted-Lowry Theory

  • Acid = proton donor (gives H⁺)
  • Base = proton acceptor (takes H⁺)
  • Example: HCl gives H⁺ to water → H₃O⁺ forms

3. Lewis Theory

  • Acid = accepts electron pair
  • Base = donates electron pair
  • Example: BF₃ (acid) accepts lone pair from NH₃ (base)
Easy tip to remember: Arrhenius = H⁺/OH⁻ in water | Bronsted-Lowry = proton transfer | Lewis = electron pair transfer. Each theory is broader than the previous one.
Want me to answer the remaining questions (Q2, Q3, Q4, or Unit 2 questions) as well?
