Instructions

To balance a chemical equation, enter an equation of a chemical reaction and press the Balance button. The balanced equation will appear above.

• Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F.
• Ionic charges are not yet supported and will be ignored.
• Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will.
• Compound states [like (s) (aq) or (g)] are not required.
• You can use parenthesis () or brackets [].

Balance NH3 + H3PO4 = (NH4)3PO4 Using the Algebraic Method

To balance the equation NH3 + H3PO4 = (NH4)3PO4 using the algebraic method step-by-step, you must have experience solving systems of linear equations. The most common methods are substitution/elimination and linear algebra, but any similar method will work.

Step 1: Label Each Compound With a Variable

Label each compound (reactant or product) in the equation with a variable to represent the unknown coefficients.

a NH3 + b H3PO4 = c (NH4)3PO4

Step 2: Create a System of Equations

Create an equation for each element (N, H, P, O) where each term represents the number of atoms of the element in each reactant or product.

N: 1a + 0b = 3c H: 3a + 3b = 12c P: 0a + 1b = 1c O: 0a + 4b = 4c

Step 3: Solve For All Variables

Use substitution, Gaussian elimination, or a calculator to solve for each variable.

Using Substitution or Elimination

• 1a - 3c = 0
• 3a + 3b - 12c = 0
• 1b - 1c = 0
• 4b - 4c = 0

Using Linear Systems / Algebra

Use your graphing calculator's rref() function (or an online rref calculator) to convert the following matrix into reduced row-echelon-form:

[ 1 0 -3 0] [ 3 3 -12 0] [ 0 1 -1 0] [ 0 4 -4 0] The resulting matrix can be used to determine the coefficients. In the case of a single solution, the last column of the matrix will contain the coefficients. Convert to RREF and Solve Step-by-Step

Simplify the result to get the lowest, whole integer values.

• a = 3 (NH3)
• b = 1 (H3PO4)
• c = 1 ((NH4)3PO4)

Step 4: Substitute Coefficients and Verify Result

Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced.

O	4	4	✔️

Since there is an equal number of each element in the reactants and products of 3NH3 + H3PO4 = (NH4)3PO4, the equation is balanced.

Balance NH3 + H3PO4 = (NH4)3PO4 Using Inspection

The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element in NH3 + H3PO4 = (NH4)3PO4 must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), this principle is used to balance one element at a time until both sides are equal and the chemical equation is balanced.

Step 1: Count the number of each element on the left and right hand sides

Reactants (Left Hand Side)			Products (Right Hand Side)
Reactants	Products
NH3	H3PO4	Total	(NH4)3PO4	Total
N	1	1	3	3	❌
H	3	3	6	12	12	❌
P	1	1	1	1	✔️
O	4	4	4	4	✔️

Step 2: Multiply coefficients for compounds to balance out each element

For each element that is not equal, try to balance it by adding more of it to the side with less. Sometimes there may be multiple compounds with that element on one side, so you'll need to use your best judgement and be prepared to go back and try the other options.

1. N is not balanced. Add 2 molecules of NH3 to the reactant (left-hand) side to balance Nitrogen: 3NH3 + H3PO4 = (NH4)3PO4

   Reactants	Products
   N	3	3	✔️
   H	12	12	✔️
   P	1	1	✔️
   O	4	4	✔️

Step 3: Verify that the equation is balanced

Since there are an equal number of atoms of each element on both sides, the equation is balanced.

3NH3 + H3PO4 = (NH4)3PO4

Practice Balancing

NH3 - + + H3PO4 - + = (NH4)3PO4 - +

Reactants	Products
N	1	3	❌
H	6	12	❌
P	1	1	✔️
O	4	4	✔️

Hint: The sum of the balanced coefficients is 5. See Step-By-Step Solution
