We can find a compound is acid or base by using litmus test.
Acides turnes red litmus to blue colour, in case of base it turnes blue litmus to red.(or) According to arrhenius priniciple Acid will give H+ ions in aqueous (water) solution.where as Bases will gives OH- ions.
Chain growth or addition polymerisation It includes a series of reaction each of which consumes a reactive particle and generates another similar one. The reactive molecule m

Acoording To Arrhenius TheoryBase:-an Arrhenius base is a substance that dissociates in water to form hydroxide (OH−) ions; that is, a base increases the concentration of OH− ions in an aqueous solution.Acid:-an Arrhenius acid is a substance that dissociates in water to form hydrogen ions (H+); that is, an acid increases the concentration of H+ ions in an aqueous solution
