Differentiate between acids and bases on the basis of their pH values. Give an example of each type. keep it simple

differences

Any compound with a pH value between zero to seven is considered acidic, whereas a pH value between seven to fourteen is a base. An acid is called a proton donor, while a base is called a proton acceptor (Kolb, 1978).

examples are:

baking soda is basic (pH = 9.0).

Orange juice is mildly acidic (pH = approximately 3.5)

The environment in your stomach is highly acidic (pH = 1 to 2).

hope that helps thanks

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
