Acids

Bases

The taste of them is sour.

The taste of these is bitter.

Acids cause blue litmus to become red.

Blue litmus' colour does not alter as a result of bases.

Red litmus remains the same colour when exposed to acids.

Properties of acids

  • Acids have a tendency to corrode.
  • They are effective electrical conductors.
  • Their pH levels are never greater than 7.
  • These chemicals react with metals to form hydrogen gas.
  • Acids have a sour flavour.
  • Examples: Sulfuric acid [H2SO4], Hydrochloric acid [HCl], and Acetic acid [CH3COOH].

Properties of bases

  • When touched, they reveal a soapy texture.
  • When these compounds are dissolved in water, hydroxide ions (OH- ions) are released.
  • The aqueous solutions of bases are effective electrical conductors.
  • Bases have pH values that are always higher than 7.
  • Bases have the power to turn red litmus paper blue and have an unpleasant taste.
  • Examples: Sodium hydroxide [NaOH], milk of magnesia [Mg(OH)2], and calcium hydroxide [Ca(OH)2].

Summary:

State differences between Acids and Bases.
