Question

Which of the following is an electrolyte?a)KCN b)Al2(CO3)3 c)Ag2Sd)Fe(OH)3

Answer 1

KCN is an electrolyte

Step-by-step explanation:

Firstly, we need to define electrolyte

An electrolyte is a substance that conducts electricity when dissolved in water. An electrolyte is a medium containing ions that are electrically conducting through the moving ions.

A good electrolyte includes soluble salts, acids, bases that dissolved in a polar solvent

Note that, all group one elements are soluble and potassium is a group one element

When KCN is dissolved in water, it dissociates into the following ions

`\text{KCN }\rightarrow K^++CN^-`

Hence, KCN is a good and strong electrolyte because of its strongly basic nature, and also, it is soluble in water.
