H2SO4 + KOH = K2SO4 + H2O

Balanced Chemical Equation – Solution

H2SO4 + 2KOH → K2SO4 + 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): H2SO4 is an acid, KOH is a base.

Sulfuric Acid + Potassium Hydroxide = Potassium Sulfate + Water

Reaction Type

Double Displacement (Metathesis)

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