acid bases and salts notes
Answers
Answer:
Bases
A base gives bitter taste. A base feels soapy when touched. A base turns red litmus paper blue.
Example: Caustic soda (sodium hydroxide), washing soda (sodium carbonate), potassium hydroxide, slaked line (calcium hydroxide), etc. All metal oxides, metal hydroxides, metal carbonates are base.
Chemical properties of base are just opposite to that of acids. When a base is added to acid, both neutralize each other, in such reactions respective salts are formed along with water Oxides, hydroxides, and carbonates of all metals are base
Types Of Base
On the basis of solubility in water, bases are divided into following two types:
(a) Water soluble base – Alkalis.
(b) Water insoluble base – Base.
Most of the bases are insoluble in water. Bases which are soluble in water called alkalis.
