How to Balance Copper (II) sulfate + Potassium iodide → Copper (I) iodide + Iodine gas + Potassium sulfate

How to Balance: CuSO4 + KI → CuI + I2 + K2SO4

Type of Chemical Reaction: This is a double replacement (sort of) reaction.

Word Equation: Copper (II) sulfate + Potassium iodide → Copper (I) iodide + Iodine gas + Potassium sulfate

Balancing Strategies: This is a little bit of a challenging reactions. I recommend trying to get an equal number of iodine atoms on the product side of the reaction. You can do this by changing the coefficient in front of the CuI.

You should end up with four iodine atoms on the product side of the equation.

About Balancing Chemical Equations

When balancing chemical equations our goal is to have the same number of each type of atom on both sides of the equation.

Only change the coefficients (these are the numbers in front substances).
Coefficients are the numbers in front of the molecule.
Never change the subscripts (the small numbers after elements).
Coefficients are the numbers in front of the molecule.
