Answer:
D. Kb = 1.8 × 10⁻⁵
Explanation:
The strongest base has the largest Kb value.
The largest Kb value has the smallest negative exponent.
So, the strongest base has Kb = 1.8 × 10⁻⁵.
The value of base dissociation constant (Kb) which represents the strongest base is 1.8×10⁻⁵.
Strong bases are those bases which completely dissociates into their ions and have high pH value in between 7 and 14.
pH value of any base is directly proportional to the value of base disssociation constant (Kb), means high value of Kb will indicates high value of pH i.e. hing basic strength. So, highest value of Kb is 1.8×10⁻⁵.
Hence 1.8×10⁻⁵ Kb value shows strong base.
