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].
State differences between Acids and Bases.
Acids have a sour flavour, while bases have a bitter flavour. Bases do not alter the colour of the blue litmus paper, but acids do. Bases with china rose indicator produces green colour, while acids with it produce dark pink colour.
