The beauty of chemistry is that the only “accurate” and “correct” is. Balance the equation fe(oh)3 + h3po4 = fepo4 + h2o using the algebraic method.

Label each compound with a variable. Label each compound (reactant or product) in the equation with a variable to represent the unknown coefficients. A fe(oh) 3 + b h 3 po 4 = c fepo 4 + d h 2 o. Create a system of equations. Fepo 4 + h 3 po 4 → h 3 [fe(po 4) 2] [ check the balance ] iron(iii) orthophosphate react with phosphoric acid to produce.

In this video we'll balance the equation H3PO4 + Fe(OH)2 = H2O + Fe3(PO4)2 and provide the correct coefficients for each compound.

To balance H3PO4 + Fe(OH)2 = H2O + Fe3(PO4)2 you'll need to be sure to count all of atoms on each side of the chemical equation.

Once you know how many of each type of atom you can only change the coefficients (the numbers in front of atoms or compounds) to balance the equation for Phosphoric acid + Iron (II) hydroxide.

Important tips for balancing chemical equations:

Only change the numbers in front of compounds (the coefficients).
Never change the numbers after atoms (the subscripts).
The number of each atom on both sides of the equation must be the same for the equation to be balanced.
