Hey! BYJU’S Achievers series, join this Mission Mid-Terms series to revise all the important concepts in your class 10 Science chapter 2, Acids, Bases and Salts.
Some of the topics covered in this class by Kriti Ma’am are as follows:
- The reaction of metallic oxides with acids
- The reaction of a non-metallic oxide with base
- Importance of pH in everyday life
- pH of Salts
- Chemicals from common salt
Acid-base indicators are dyes or dye mixtures that are used to detect the presence of acids and bases. When an acid reacts with a metal, hydrogen gas is produced and salt is formed. When a base reacts with a metal, a salt with a negative ion composed of the metal and oxygen is formed. Because they produce hydrogen and hydroxide ions, acidic and basic solutions in water conduct electricity. Learn more about acids and bases in this online class.

mam is lichens a symbiosis
Lichen is a symbiotic association between algae and fungi. Alga is the source of food as it can synthesize food for this simple symbiotic association and the fungus absorbs water and minerals for the algae. The fungal component in a lichen is called mycobiont and the algal component is called phycobiont.
