Balanced Chemical Equation – Solution
Mg(OH)2 + 2HCl → MgCl2 + 2H2O
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): Mg(OH)2 is a base, HCl is an acid.
Brucite + Hydrogen Chloride = Magnesium 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.
Reactants:
Mg(OH)2 – Magnesium hydroxide
- Other names: Magnesium dihydroxide.
- Appearance: White solid.
HCl – Chlorane
- Other names: Hydrochloric acid.
- Appearance: Colorless, transparent liquid, fumes in air if concentrated.
Products:
MgCl2
- Names: Magnesium chloride.
- Appearance: White or colourless crystalline solid.
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.
