what are acids , bases , and salts ?
Answers
Answer:
Acids
- They turn blue litmus red.
- Have two forms - Organic or mineral acids.
- Give H+ ions when dissolved in water.
- Are sour in taste.
- Value on pH scale is from 0 to 7.
Bases -
- Turn red litmus blue.
- Are corrosive in nature.
- Give OH- ions when dissolved in water.
- Are bitter in taste.
- value on pH scale is from 7 to 14
Salts-
- Formed by the reaction of Acids and Bases.
- Are of 3 types - Acidic salts, Basic salts and Neutral salts.
- Are ionic in nature.

Explanation:
Acid
Any of various water soluble compounds having a sour taste and capable of turning litmus paper red and reacting with a base to form a salt.
pH of acid is 0 to less than 7.
Realese H+ ion in aqueous solution.
Example- Sulphuric acid.
Nitric acid. etc
Base
Any of various water soluble compounds capable of turning litmus paper blue and reacting with an acid to form a salt and water.
Release OH- ion in aqueous solution.
pH of base is greater than 7 but less than 14.
Example- Sodium hydroxide
Magnesium hydroxide etc.
Salt
Salt is a compound formed by replacing hydrogen in an acid by a metal (or radical that acts like a metal).
or
Formed by the reaction of acid and base.
