Neutralization is a chemical reaction in which an acid and a base react quantitatively with each other resulting in salts and water as products. The reaction involves combination of H+ and OH– ions resulting in formation of water.
Acid + Base (alkaline) → Salt + Water
H2SO4 +2( NaOH) → Na2SO4 + 2(H2O)
Sulphuric Acid + Sodium Hydroxide → Sodium Sulfate + Water
H+(aq) + OH–(aq) → H2O(l)
Phenolphthalein is an acid/base artificial indicator. It is colorless when it is added to an acid and changes color to pink when added to a base. Lime water is a calcium hydroxide solution, Ca(OH)2, which is a base, used in this experiment.
