Bases

Definition

Characteristics of bases

Bases can be identified as:

• Tastes bitter
• Converts Red litmus Blue
• Ionizes to form ions

Reactions

With Metals

Metals are usually basic in nature, so they do not react except in a few cases where the metal is amphoteric like Zn. Then it forms a Salt and Hydrogen Gas.

where is Sodium Zincate.

With Non-metal oxides

Non metal oxides are acidic in nature, so they perform a Neutralisation Reaction.

With Water

Bases give ions when they are dissolved in water.
