Question

Which one among Ag+ and K+ has more polarizing power amd why?

Answer 1

Answer:

Ag+ has more polarizing power than K+.

Explanation:

Since the polarizing power among the cations increases as the size (ionic radii) decreases. Ag+ has ionic radii of 115 pico metre (pm) whereas K+ has size of 138 pm. Hence, the smaller cation i.e. Ag+ will have the more polarizing power as compared to the K+ cation.
