KOH (potassium hydroxide) + P2O5 ⟶ H_2O (water) + K3PO4
Balanced equation
![Balance the chemical equation algebraically: KOH + P2O5 ⟶ H_2O + K3PO4 Add stoichiometric coefficients, c_i, to the reactants and products: c_1 KOH + c_2 P2O5 ⟶ c_3 H_2O + c_4 K3PO4 Set the number of atoms in the reactants equal to the number of atoms in the products for H, K, O and P: H: | c_1 = 2 c_3 K: | c_1 = 3 c_4 O: | c_1 + 5 c_2 = c_3 + 4 c_4 P: | 2 c_2 = c_4 Since the coefficients are relative quantities and underdetermined, choose a coefficient to set arbitrarily. To keep the coefficients small, the arbitrary value is ordinarily one. For instance, set c_2 = 1 and solve the system of equations for the remaining coefficients: c_1 = 6 c_2 = 1 c_3 = 3 c_4 = 2 Substitute the coefficients into the chemical reaction to obtain the balanced equation: Answer: | | 6 KOH + P2O5 ⟶ 3 H_2O + 2 K3PO4](../image_source/b5c99a562a0edc2783c9aabf5bef56b1.png)
