HCl + NaOH = NaCl + H2O

Balanced Chemical Equation – Solution

HCl + NaOH → NaCl + H2O

The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.

Chemical Reaction Information

This is an acid-base reaction (neutralization): HCl is an acid, NaOH is a base.

Hydrogen Chloride + Sodium Hydroxide = Sodium Chloride + Water

Reaction Type

Double Displacement (Acid-Base)

Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.


HCl – Chlorane, Hydrogen chloride

  • Other names: Hydrochloric acid.
  • Appearance: Colorless, transparent liquid, fumes in air if concentrated.


  • Names: Sodium hydroxide.
  • Appearance: White, waxy, opaque crystals; White hygroscopic solid in various forms.


NaCl – Sodium chloride

  • Other names: Salt , NaCl.
  • Appearance: Colorless cubic crystals.

H2O – Water, oxidane

  • Other names: Water (H2O), Hydrogen oxide, Hydrogen hydroxide.
  • Appearance: White crystalline solid, almost colorless liquid with a hint of blue, colorless gas.
