Assertion (A) The \(\mathrm{pH}\) of a buffer solution containing equal moles of acetic acid and sodium acetate is 4.8 ( \(\mathrm{p} K_a\) of acetic acid is 4.8).
Reason (R) The ionic product of water at \(25^{\circ} \mathrm{C}\) is \(10^{-14} \mathrm{~mol}^2 . \mathrm{L}^{-2}\). The correct answer is
- A Both (A) and (R) are true and (R) is the correct explanation of (A)
- B Both (A) and (R) are true and (R) is not the correct explanation of (A)
- C (A) is true but (R) is not true
- D (A) is not true but (R) is true
Answer & Solution
Correct Answer

- Assertion(A): The maximum covalency of Si and Ge is 6 but that of carbon is 4.
Reason (R): Due to the presence of d-orbitals in Si and Ge, both these elements can undergo \(\mathrm{sp}^3 \mathrm{~d}^2\) hybridisation and covalency of 6 is possible. Carbon has no d-orbitals in it and hence its covalency is 4.
