What are the similarities and differences between - a) Natural detergents and man-made detergents b) Soap and synthetic detergent c) Both soap and soap for washing clothes d) Modern cement and ancient cement
Answers
a) Natural detergents and man-made detergents
Natural detergents are the naturally occurring/derived plants (For instance, Soapberry commonly called Reetha, Scientific Name: Sapindus mukorossi) which can be used as detergents.
The similarity between the both is that both can be used as surfactants i.e. to remove oil and grease. One difference between the two is that natural detergents do not harm the environment.
Man-made detergents are the chemically synthesized compounds which are also used as surfactants and are much more efficient than the natural detergents. However, these are harmful to the environment.
b) Soap and synthetic detergent
Soap and synthetic detergents both are surfactants that remove grease and oil from surfaces and are used for washing purposes.
However, soap is made up of oil which is extracted from naturally occurring products, whereas, synthetic detergents are man-made and are synthesized chemically and derived from artificial products.
c) Both soap and soap for washing clothes
Normal body soap and soap for washing clothes are both meant for washing/cleaning purposes and therefore are effective in removing grease/oil. However, body soap/normal soap is much milder than the soap for washing clothes.
d) Modern cement and ancient cement
Ancient cement varies a lot depending upon the regions.
Egyptians used calcined Gypsum as cement while Egyptians heated limestone to make lime and used it as cement whereas, Portland cement, (which is the most commonly used modern cement) is composed of silica, lime, and alumina.
The similarity between the two is that both modern and ancient cement relied on the binding property of lime (i.e. CaO).
Answer:
natural detergent and man made detergent difference is : 1. Natural detergents are occurs naturally 2. man made detergent are synthesized chemically and derived from artificial products
and
similarity is : both can be used as surfactants
