Answer
3 KOH + 1 H₃PO₄ → 1 K₃PO₄ + 3 H₂O
Step-by-step explanation
Given that:
_KOH + _H₃PO₄ → _K₃PO₄ + _H₂O
This is an acid-base reaction (neutralization): H₃PO₄ is an acid, and KOH is a base.
The unbalanced equation given can be balanced as follows:
Put 3, 1, 1, and 3 as the coefficients of KOH, H₃PO₄, K₃PO₄, and H₂O respectively. Thus, the balanced equation is:
3 KOH + 1 H₃PO₄ → 1 K₃PO₄ + 3 H₂O
