Question

Which of the following has the highest degree of ionization?

• A. $1MN{H}_3$
  
• B. $0.001MN{H}_3$
  
• C. $0.1MN{H}_3$
  
• D. $0.0001MN{H}_3$
  

Answer 1

The correct option is D $0.0001MN{H}_3$


As concentration of solution decreases, degree of dissociation of weak electrolyte increases.

$\alpha =\sqrt{\frac{K_b}{\text{Concentration}}}$
degree of dissociation is inversely proportional to the square root of the concentration of the base.
