In medicine, neutralization reactions are used to treat acidity or
gastric problems caused by excess acid in the stomach. Antacids
are medicines that contain bases such as sodium bicarbonate or
magnesium hydroxide that can neutralize the excess acid and
relieve the symptoms. ///In agriculture, neutralization reactions
are used to control the pH of the soil, which affects the growth
of plants. If the soil is too acidic or too basic, it can be
neutralized by adding appropriate substances such as lime,
wood ash, or sulfur. /// In wastewater treatment,
neutralization reactions are used to reduce the damage created
by the effluents. Different chemicals are used to neutralize the
toxicity of the waste before they can be disposed of. Some
common examples are sodium bicarbonate, magnesium
hydroxide, calcium oxide, or calcium carbonate. /// In
nanomaterial synthesis, neutralization reactions are used to
facilitate the chemical reduction of metal precursors. The heat
of a neutralization reaction is used to create nanoparticles of
various metals. //In our digestive systems, neutralization
reactions are used to regulate the pH of the food that moves
between our stomach and intestines. The stomach produces
acid to digest the food, but the intestines need an alkaline
environment to absorb the nutrients. Bicarbonate is produced
to neutralize the acid and create a favorable condition for the
intestines
