Step-by-step explanation:
Neutralization reaction -
The reaction of an acid and base to yield a salt and water , is a type of neutralization reaction .
The reaction of potassium hydroxide and phosphoric acid is a type of neutralization reaction ,
Hence , the reaction is as follows -
KOH (aq) + H₃PO₄ (aq) ----> K₃PO₄ (aq) + 3H₂O (l)
The reaction after balancing the atoms on the reactant side and on the product side is -
3 KOH (aq) + H₃PO₄ (aq) ----> K₃PO₄ (aq) + 3H₂O (l)
