Answer:
3H₃PO₄ + 3KOH → K₃PO₄ + 3H₂O
Explanation:
To balance the chemical equation:
H₃PO₄ + KOH → K₃PO₄ + H₂O
We can balance it by following these steps:
1. Balance the atoms other than hydrogen and oxygen. In this case, we have one phosphorus (P) atom on both sides and one potassium (K) atom on the right side. The equation becomes:
H₃PO₄ + KOH → K₃PO₄ + H₂O
2. Balance the oxygen atoms by adding water (H₂O) molecules as needed. In this case, we have four oxygen (O) atoms on the left side and five oxygen (O) atoms on the right side. To balance the oxygen, we add a water molecule (H₂O) to the left side:
H₃PO₄ + KOH → K₃PO₄ + H₂O
3. Balance the hydrogen atoms by adding hydrogen ions (H⁺) as needed. In this case, we have three hydrogen (H) atoms on the left side and two hydrogen (H) atoms on the right side. To balance the hydrogen, we add three hydrogen ions (H⁺) to the right side:
H₃PO₄ + KOH → K₃PO₄ + 3H₂O
4. Balance the charges by adding potassium ions (K⁺) as needed. In this case, we have one positive charge on the left side and three positive charges on the right side. To balance the charges, we add three potassium ions (K⁺) to the left side:
3H₃PO₄ + 3KOH → K₃PO₄ + 3H₂O
