Chemical properties or chemical reaction of base

Chemical properties or chemical reaction of base:

  • Base are bitter in taste.
  • Base are slippery in touch.
  • Base turn red litmus paper into blue.
  • Which base dissolve in water called alkalis.
  • Base react with acid and produced salt and water.

Chemical reaction of base

1) Reaction with Metals:

When the strong bass react with active metals to produce salt  and Hydrogen gas.

Metal +  Base —-> salt + hydrogen gas

Zinc solid react with aqueous sodium hydroxide to produce sodium zincate  and hydrogen gas.

2) Reaction with non metallic oxide:

base react with non metallic oxide carbon dioxide with basic substance slaked lime to produce salt and water.

Base+ Non metallic oxide  —->  Salt + water

3) Reaction between acid and bases:

The reaction between acid and base to produce salt water.

Acid+  Base —–>  salt + water

When hydronium ion H+ react with hydroxide ion OH- to get neutralize and produce water.

Example: when sodium hydroxide react with sulphuric Acid to produce sodium sulphate and water
