Advantages and Disadvantages Detergents
95. Detergents : Detergents are sodium or potassium salts of sulphonic acids of hydrocarbons of alkene type. They have –SO3H group, i.e., sulphonic acid group.
Examples :
(i) Sodium lauryl sulphate
(ii) Sodium dodecylbenzenesulphonate
96. Advantages of Detergents over soaps :
(i) Detergents work well even with hard water but soaps do not.
(ii) Detergents may be used in saline or acidic water
(iii) Detergents are more easily soluble in water than soaps.
(iv) Detergents can be used for washing woolen garments whereas soaps cannot be used.
(v) Detergents having linear hydrocarbon chain are biodegradable.
97. Disadvantages of Detergents over Soaps :
(i) Synthetic detergents having branched hydrocarbon chain are not fully biodegradable, i.e., they are not decomposed by micro-organisms in sewage and create water pollution.
(ii) They are more expensive than soaps. Let us take up differences between soaps and detergents.
