Question

Given your results of Part III, predict the solubility of the following mixtures. Explain your answers. a) Methanol (CH,OH) in water. b) Hexane (CH3CH2CH2CH2CH2CH) and cyclohexane c) Hexane and water

Answer 1

( a ) soluble

( b ) soluble

( c ) insoluble

Step-by-step 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 ,

( a )

Methanol and water as we know are both polar species , hence , according to the principle - soluble .

( b )

Hexane and cyclohexane

Both the species are polar species , hence , according to the principle - soluble .

( c )

Hexane and water

In this case ,

Hexane , is non polar and water is polar , hence , the mixture will be non soluble .
