Question

Correct order of solubility with fajans rule with explanation

Answer 1

Answer:

Ionic compounds are more soluble in water or in aqueous medium. <br> According to Fajan's rule. <br> Size of the cation increases the ionic character also increases. Ionic character

size of cation (if anion is same ) The order of size of cations is <br>

<br>

The order of ionic character and hence, of solubility in water is as <br>

Answer 2

Answer: C

Explanation:The Solubility is inversely proportional to the covalent character.
