Molecular complete and abbreviated ionic equation of potassium hydroxide and sulfuric acid

2KOH + H2SO4 = K2SO4 + 2H2O

When substances are found in water, dissociation occurs, the elements disintegrate into parts – ions. Writing down the usual equation does not take into account that the ionic react.

Let us write down the complete ionic equation. In the left and right parts there are identical K + cations and SO4- anions.
2K⁺+ 2OH^– + 2H⁺+ SO4^2- = 2K⁺+ SO4^2-+ H2O

Let us reduce these ions on the left and right sides. Let’s get a short ionic equation showing that the reaction proceeds with the formation of water.

2OH^– + 2H⁺ = 2H₂O.
