Solution:
*Multiple options can be correct
QUESTION: 3

The pH of 0.1 M solution of the following salts increases in the order      [JEE 1999]

Solution: NaCN is prepared from strong Base and weak acid therefore it's ph will be very high after that NaCl is made up of strong acid as well as strong Base so it's ph will be less than NaCN after that NH4Cl is from weak Base and strong acid so it'll be less in ph than NaCl but more than HCl which is a strong acid
*Multiple options can be correct

[JEE 2008]

Solution:
*Multiple options can be correct
QUESTION: 12

2.5 mL of M weak monoacidic base (Kb = 1 × 10-12 at 25°C) is titrated with M HCl in water at 25°C. The concentration of H+ at equivalence point is (Kw = 1 × 10-4 at 25°C)          [JEE 2008]

Solution:
*Multiple options can be correct
QUESTION: 13

Aqueous solutions of HNO3, KOH, CH3COOH, and CH3COONa of identical cocentrations are provided. The pair(s) of solutions which form a buffer upon mixing is(are).              [JEE 2010]

Solution:

A buffer solution consists of weak acid and its salt with strong base or weak base and its salt with strong acid.
If we limit the amount of nitric acid, then it will partially convert sodium acetate to acetic acid.
CH3COONa+HNO3​→CH3​COOH+NaNO3
Now the solution contains acetic acid (weak acid) and sodium acetate (salt with strong base NaOH). So, it will become a buffer solution.
Acetic acid (weak acid) and sodium acetate (salt with strong base NaOH) also form a buffer solution.
Hence both C and D are correct.

*Multiple options can be correct
