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
