NEET Chemistry Ionic Equilibrium MCQ Question
What is the ionization constant (K_b) of a 0.004M hydrazine solution if its pH is 9.7?
5.98 × 10^-6
67 × 10^-10
5.98 × 10^-5
00 × 10^-14
Correct Answer
Detailed Explanation
From the given pH of 9.7, we calculate [H+] and use the ionic product of water (K_w) to find [OH-]. The ionization constant K_b is then calculated using the concentration of OH- ions.
