A

`[SnO_2]SnO_(3)^(2-) : Na^(+)`

B

`[SnO_2]Sn^(4+) : O^(2-)`

C

`[SnO_2]Na^(+) : OH^(-)`

D

`[SnO_2]Sn^(4+) : OH^(-)`

Text Solution

Verified by Experts

The correct Answer is:
A
`SNO_(2) +NaOH rarr underset("sodium stannate ")(Na_2SnO_3) "     " [SnO_2]SnO_(3)^(2-)`

There are certain substances which behave as normal, strong electrolytes at low concentration but at higher concentration they behave as colloidal solution due to the formation of aggregated particles. Such colloids are called associated colloids and the aggregated particles are called micelles. Soaps anddetergents are the examples of associated colloids. The formation of micelles takes place above certain concentration called critical micellization concentration (CMC) and a characteristic temperature called Kraft temperature (T_k) . Micelles are formed only
