Why does `ZnO` show increased electrical conductivity and turns yellow on heating?

A

`0.1M NH_(4) OH`

B

`"0.01 M "NH_(4)OH`

C

Both equal

D

None

Text Solution

Verified by Experts

The correct Answer is:
B

From Ostwald's dilution law `alpha prop (1)/(sqrt(c ))`
Less the value of C, more will be `alpha` hence stronger will be base. Ans. `(2)`.
