The purpose of soap or detergent in washing is to reduce friction between the oil drops carrying dirt particles and the water so that they may mix wit...
No, it is not possible. Detergents produce foam in any type of water; whether hard or soft Therefore, a distinction between the two cannot be made. Ho...
Oxidising agents are the substances which either on their own or on reacting with another substance release oxygen in order to carry oxidation reactio...
The distinction can be made by the following, tests: (a) Dip a strip of blue litmus paper separately in both alcohol and carboxylic acid taken in tw...
When ethyne is burnt in oxygen, a large quantity of heat along with light is produced. The heat evolved can be used for gas welding which is usually c...
Ethanoic acid (CH3COOH) has one oxygen atom more and two hydrogen atoms less than ethanol (C3H5OH). In general, Loss of hydrogen is known as oxida...
