Answer to Question #140710 in General Chemistry for Javier

Question

Water is a polar solvent; CCl4 is a nonpolar solvent. In which solvent is each of the following more likely to be soluble?

KCl, ionic

is it Water Or Carbon tetrachloride

Answer 1

KCl soluble in water.

Explanation:

KCl is a ionic compound ( K⁺ + Cl^–), in the solid state of it electrostatic force of attraction strongly binds the K⁺ and Cl^– together.

The ionic compound will get soluble in a solvent when solvent molicules interact with each of K⁺ and Cl^– ions more strongly than interaction exist between K⁺ and Cl^–

Water is a polar solvent it interact with K⁺ and Cl^– ions by its opposite ends of

polar ^δ–O—H^δ+ bond.

Being a no polar solvent CCl4 unable to do such interaction , that's why KCl can't be soluble in CCl4.
