of the first set of experiments is to find out and record the colour changes that are observed after a certain indicator is mixed with acids and bases to form a colour reaction. For example, a typical base according to the Arrhenius definition is sodium hydroxide (NaOH NaOH H2O Na( aq ) OH-( aq ) The Arrhenius definition of acids and bases explains a number of things. Following the same steps as before one drop of the chosen weak acid, Sulfuric Acid 1M ( H2SO4 ) was placed on the tile using an eyedropper. Acids and bases are really important in functioning cell. Once the selected indicator has been mixed with a acid that is both weak and strong and a base/alkali that is both weak and strong we are to record the colour and choose another indicator. He said, Aqueous solutions of acids give H ion. Acids tastes sour, bases tastes bitter and bases are slippery. However, the Brønsted-Lowry definition also explains why substances that do not contain OH- can act like bases. . For example, sulfuric acid is a strong acid and it has ability to hold the water therefore if it poured on a live tissue it will be demolished immediately.

The pH scale ranges from 0. The Arrhenius definition also explains Boyle's observation that acids and bases counteract each other.
