Question

Which among the following is the correct increasing order of solubility in water?

A CsF< MgF2< Nak< FeCl3
B FeCl3<NaF <MgF2< CSF
C Fecl3< MgF2<CsF< NaF
D FeCl3 MgF2 < Nak< CSF
​

Answer 1

Answer:

option b is the correct order for incrssing solubility in warter

Answer 2

The correct increasing order of solubility in water is (B) FeCl3<NaF <MgF2< CS

Explanation:

1.Solubility of a compound is directly proportional to atomic size of the metals. So, in a group, the atomic size increases, so the solubility of the metal salt will increase moving down the group.

2.solubility, degree to which a substance dissolves in a solvent to make a solution (usually expressed as grams of solute per litre of solvent). Solubility of one fluid (liquid or gas) in another may be complete (totally miscible

3.e.g, methanol and water or partial (oil and water dissolve only slightly).
