Question

1.Two aqueous solutions P and Q have pH of 5 and 13 respectively. The correct inference is that:
(a) solution P is of HCl and Q is of NH4OH
(b) solution P is of CH3COOH and Q is of Ca(OH)2
(c) solution P is of HNO3 and Q is of NH4OH
(d) solution P is of CH3COOH and Q is of NaOH

Answer 1

Answer:

your answer is

option c

hope it is helpfull

Answer 2

(d) solution P is of CH3COOH and Q is of NaOH is correct about P and Q.

1. pH scale ranges from 0 to 14 and provides measure of strength of acid and base. Range from 0 to 7 indicates acidic nature and range 7 to 14 is indicative of basic nature. pH is neutral.
2. Strong acids, which completely dissociate, have their pH near 0. Similarly, strong bases, have their pH near 14.
3. Weak acids and weak bases have their pH near 7.
4. pH 5 is near 7, hence it is a weak acid therefore, it should be acetic acid.
5. pH 13 is near 14, hence it a strong base therefore, it should be sodium hydroxide.
