Bases are those chemical substances which have ability to accept a proton. Strong bases have ability of completely ionized in water. They have the ability to accept proton from the weak acid in the absence of water. The examples of strong base are potassium hydroxide, barium hydroxide and sodium hydroxide etc. Weak bases do not completely ionize in the solution. They have less ability to accept a proton as compare to strong bases. The common examples of weak basis are pyridine and ammonia. Moreover, weak bases have higher concentration of H+ in its solution as compare to strong base because it does not completely protonated.
