What is alkali and its examples?
Alkalis can be defined as Bases that are soluble in water are called Alkalis. example : Sodium hydroxide, Potassium hydroxide,etc . Important point to know about Alkalis are that all alkalis are bases but all bases are not Alkalis.
Which of the following is an example of alkalis?
Alkalis are bases that dissolve in water. Common alkali-containing substances are lyes, ammonia, hair-relaxing agents, nonphosphate detergents, dishwasher soaps, and disk batteries. Lyes are alkaline agents that contain sodium hydroxide (NaOH), potassium hydroxide (KOH), or calcium hydroxide (Ca(OH)2).
What alkalis do we use in everyday life?
Alkalis are found in everyday products like:
- Oven cleaner.

- Drain unblocker.
What is use of alkali?
Uses of common Alkalis Sodium hydroxide is used to make paper, detergents and soap. Potassium hydroxide is used by farmers to make acidic soil more alkaline so that plants will grow better in it, and is also used as the electrolyte in alkaline, Ni-Cd, and Ni-MH batteries.
Why is alkali important?
The alkali metals react readily with atmospheric oxygen and water vapour. (Lithium also reacts with nitrogen.) They react vigorously, and often violently, with water to release hydrogen and form strong caustic solutions. Sodium is by far the most important alkali metal in terms of industrial use.
What are the three uses of alkalis?
(1) Sodium hydroxide is used to make paper,detergents and soap. (2) Potassium hydroxide is used in farming to make acidic soil more alkaline so that plants will grow better in it, and is also used as the electrolyte in alkaline, Ni-Cd, and Ni-MH batteries. (3) Calcium carbonate is used as a building material.
