Acids and bases are chemicals that have opposite chemical properties.
Acids have a sour taste.
bases in contrary to this have a bitter taste.
When acids and bases react together, they form another compound called salts.
The properties of acids:
Contain H+ ions (hydrogen ions)
Form hydrogen ions when dissolved in water (H20)They are H+ proton donors (hydrogen ions)Taste sourCan corrode metals (are corrosive)Burn Conduct electricity when dissolved in water (they are electrolytes)Have a pH less than 7Cause blue litmus paper to turn redReact with bases to form salt and water

Contain OH- ions (hydroxide ions)They are H+ proton acceptors (hydrogen ions)Taste sourThey are corrosiveFeel slipperyConduct electricity when dissolved in water (they are electrolytes)Have a pH greater than 7Cause red litmus paper to turn blue React with acids to form salt and water
