Question

Indicate the type of solute-solvent interaction that is most important in each of the following solutions: a KBr in water b hexane, C6 H14, in gasoline c ammonia in wate​

Answer 1

Answer:

n-Octane is non polar and can dissolve non-polar solutes. It cannot dissolve polar (and ionic) solutes.

Cyclohexane is non-polar. Hence, easily soluble in n-octane.

Methanol and acetonitrile are polar and have very low solubility in n-octane.

KCl is ionic compound and hence, insoluble in n-octane.

The increasing order for solubility in n-octane is as follows:

KCl<CH

3

OH<CH

3

CN<

Answer 2

Answer:

Explanation:

KBr is an ionic compound which when dissolved in water dissociates into its ionic components due to salvation by polar water molecules the interaction involved are ion-dupole force
