Balanced equation
Balance the chemical equation algebraically:
NaH2PO4 + H2O → NaOH + H3PO4
Add stoichiometric coefficients, c, to the reactants and products:
c1NaH2PO4 + c2 H2O → c3 NaOH + c4 H3PO4
Set the number of atoms in the reactants equal to the number of atoms in the products for H, Na, O and P:
H: 2c+2C2=C3+3C4 Na: C1=C3
O: 4C1+C2 C3 +4 C4
P: c1=C4
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 c1 = 1 and solve the system of equations for the remaining coefficients:
C1 = 1 C2=1
C3 = 1 C4=1
Substitute the coefficients into the chemical reaction to obtain the balanced
equation:
