Balanced Chemical Equation – Solution
3KOH + H3PO4 → K3PO4 + 3H2O
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): KOH is a base, H3PO4 is an acid.
Potassium Hydroxide + Phosphoric Acid = Tribasic Potassium Phosphate + Water
Double Displacement (Metathesis)
Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.
