How to Balance Lead (II) and up nitrate + potassium iodide → Potassium nitrate + Lead (II) iodide

How to Balance: Pb(NO3)2 + KI → KNO3 + PbI2

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

Word Equation: Lead (II) and up nitrate + potassium iodide → Potassium nitrate + Lead (II) iodide

Balancing Strategies: In this double replacement reaction the Pb and K and switch places.

To balance the equation it is helpful to think of the nitrate (NO3) as one item. This is and explained in the video.

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.
