From a practical point of view on bases: it's slippery and it has a bitter taste--soap is basic. From a molecular point of view, bases are substance that produces hydroxide ions (OH-) in an aqueous solution. Acid is the opposite--as light is to darkness--and produces hydronium ions (H3O+) in an aqueous solution.

In chemistry, a base is a substance that can accept protons or donate electrons in a chemical reaction. Bases typically have a pH greater than 7 and can neutralize acids to form salts and water. Common examples of bases include sodium hydroxide (NaOH) and ammonia (NH3).

a basic substance is a substance which contains a hydroxl (OH) group on it.

in contrast, an acid is a substance which contains a hydrogen (H) group.

For instance:

HCl - Hydrochloric acis

NaOH - Sodium hydroxide

H2O - Hydrogen Hydroxide (also known as "water")

H2O is both an acid and a base at the same time: That's why it's nuetral!
