How can dehydration synthesis and hydrolysis reactions be modelled using household materials

The process of dehydration synthesis is a process which involves the loss of a water. So, using household materials you can make this reaction by mixing the vinegar and alcohol.

CH3COOH+CH3CH2OH⇌CH3COOCH2CH3+H2O

Hydrolysis is an opposite reaction (compared to dehydration synthesis) which involves the breakage of a bond in a molecule using water.

The reaction at home would be adding salt into water. Salts in water, will dissociate to form ions.
