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
Acids taste sour.They turns red litmus to blue where as base taste is bitter and it is slippery in nature.Bases turns blue litmus to red.
