Question

What is the correct order of electrical conductivity of following ions in water.... H+, Li+, Na+, K+, Rb+, Cs+.... Answer only if you know... Don't try to guess.... Look at my profile..... Something is written there..... ​

Answer 1

Answer:

H Cs Rb K Na Li (decreasing)

Explanation:

H has max conductivity

Cs greater than li bcoz of hydration

By the way I have cleared IJSO level 2 in class 9 and appeared level 3 in mumbai

Answer 2

Answer :- H>Cs>Rb>K>Na>Li

Explain:-

Conductivity will depend upon their state. In liquid state Li+ will be more conductive than Na+ because of its smaller size. But in hydrated state Na+ will be more conductive than Li+. In this case effetive size of Li+ ion will be more than Na+ ion as there will be more hydration of Li+ ion. Li+ will have greater charge density than Na+; so there will be more hydration of Li+ and it will be effectively larger in size than Na+ and becomes less conductive than Na+.

Hope this answer will satisfy you.
