    Using the smallest coefficient the chemical equation is written as

    3KOH (aq) + H3PO4 (aq) → K3PO4 (aq) + 3H2O (aq)

    Explanation:

    Neutralization reaction is a reaction in which acid and base reacts quantitatively to form salt and water.

    Base = potassium hydroxide

    acid = phosphoric acid.

    KOH = potassium hydroxide

    H3PO4 = Phosphoric acid

    KOH (aq) + H3PO4 (aq) → K3PO4 (aq) + H2O (aq)

    The number of atoms on both side (reactant and product) of the equation are not equal so, we need to balance it.

    3KOH (aq) + H3PO4 (aq) → K3PO4 (aq) + 3H2O (aq)

    The product are salt and water.

    Salt = K3PO4

    water = H2O

    The equation is balanced on both sides.

    The potassium atom is 3 on both sides, oxygen atom is 7 on both sides, hydrogen atom is 6 on both sides and phosphorus atom is 1 on both sides.
