Answer.
A neutralization reaction creates a solution that is pH neutral. That means when an acid of a pH less than 7 reacts with a base of a pH greater than 7, they change to a pH value closer to 7. If it is completely neutralized, the pH is 7.
Because acids release hydrogen ions (H+), and bases release hydroxide ions (OH-), the two oppositely charged ions are attracted and form water (H20). Water is always one of the products of neutralization. The other product comes from the other substances that were originally bonded to the ions of the acid and the base. These substances are now also oppositely charged and form a new compound together. That compound is always a salt. Ionic compounds are also salts.
In order to neutralize the stomach acids, an antacid is used, which is often comprised of a bicarbonate, which is a base. In this reaction, the base in the antacid and the hydrochloric acid in the stomach are the reactants, and they combine to form the products salt, water and carbon dioxide. Those products help neutralize the acids in the stomach and lessen the painful symptoms of heartburn.
Farmers and gardeners also frequently use neutralization equations to help their plants flourish. Some soil is too acidic for certain plants to thrive, so gardeners add a fertilizer that contains a base like lime in order to neutralize the soil. In this equation, the acid of the soil and the lime base are the reactants. They react to form water and salt that work to raise the pH level of the soil and ensure it’s ready for planting.
