Examples of neutralization reaction

Neutralization is the chemical reaction that produces the reactants, an acid with a base, using products such as salt and water, it is known as neutralization, and it happens because in this case, the acids have a low pH of less than 7, and bases have a high pH greater than 7.

When these acids are joined with the bases, they are chemically balanced and the same amounts are joined, the pH results in neutral 7.

For acids to be neutralization reactions, they have to be inorganic acids and organic acids, of which we mention the following:

  • Hydrochloric HCl these acids are mostly strong (inorganic acid).
  • Formic H-COOH these acids are weak (organic acid).

The bases that are used for the neutralization reactions are the inorganic ones of which we mention:

  • Sodium Hydroxide NaOH and Calcium Hydroxide Ca (OH) 2, these bases being strong.

Chemical equation of a neutralization reaction

  • Acid (inorganic or organic) + base (inorganic) – Salt + Water

Procedure of a neutralization reaction

Mostly, these neutralization reactions are used in industries, when there is a leak of a base or an acid, they have a very dangerous substance for humans, there is a procedure for this neutralization.

Steps for neutralization

    • Mark the area or zone with standardized yellow tape.
    • select personnel who will be in charge of neutralization.
    • The personnel in charge must put on personal protective equipment.
    • Pour the substance that neutralizes the spill. If it is a base, an acid is added and vice versa.
    • When the reaction occurs, more people should be avoided.
    • Pour water to dilute the substances once the reaction has finished.
    • Send the liquid to a drain.
    • Wash the area so that no residue remains.
    • Remove the signage so that staff can return to work.

15 Examples of neutralization

Below we will proceed to list some examples of neutralization in order to generate greater understanding as to how this process occurs and its reactions:

  1. Hydrochloric acid HCl with potassium hydroxide KOH.

HCl + KOH -> KCl + H2O
