Question

State whether each of the following will be more soluble in water or hexane i. Butane ii. Ch3cooh iii. K2so4

Answer 1

Explanation:

Solubility is determined by the principle , "like dissolves like" .

i.e. , if a compound is polar then it will dissolve in a polar compound only , and

if a compound is non - polar then it will dissolve in a non - polar compound only .

Hence , from the question ,

Water is a polar molecule , and hence it will dissolve only the polar molecule , i.e. , from the given options the polar molecule is , iii. K₂SO₄

Hexane , is a non - polar molecules ,  hence it will dissolve only the non polar molecule , i.e. , from the given options the non polar molecule is i. Butane .

Answer 2

The substance soluble in water is $\rm ii. CH_3COOH\;\;\; iii. K_2SO_4$

The substance soluble in hexane is  i. Butane

What is solubility?

Solubility is the measure that how much solute will be soluble in liquid.

The substance soluble in water are polar solvents. Only these substances are soluble in water.

The substance that are not soluble in water are called non-polar solvents.

The acetic acid  and potassium sulfate is soluble in water because it has polar ends that dissolve with the water.

The butane is soluble in hexane not in water because it has non-polar ends.

Thus, The substance soluble in water is $\rm ii. CH_3COOH\;\;\; iii. K_2SO_4$

The substance soluble in hexane is  i. Butane.
