difine acid and base and give there example
Answers
Answer:
Bases are substances that, when dissolved in water, have a pH level greater than seven, taste bitter, and feel slippery. They react with acids by accepting H+ ions, giving bases the ability to neutralize acids. ... In nature, an important example of a base neutralizing acid occurs in the ocean.
Answer:
An acid is a substance which produces hydrogen ions, when it is dissolved in water (e.g. hydrochloric acid(HCL), sulfuric acid (H2S04), nitric acid (HNO3))
They have a sour taste, conduct electricity, have a pH level smaller than 7, and turn blue litmus paper red.
They react with a reactive metal (all metals except copper, silver & gold) to form salt & hydrogen gas, carbonate (calcium carbonate) to form salt, carbon dioxide & water, base/alkali to form salt & water.
A base is any metal hydroxide or metal hydroxide,
They can be classified into two categories: Insoluble and soluble (alkali)
Insoluble: Metal oxides (Group 1 oxides, calcium oxide, barium oxide), metal hydroxides (Group 1 hydroxides, calcium hydroxide, barium hydroxide, aqueous ammonia)\
