Writing Equations with compounds Name: ___
eg. A solution of Lead Nitrate reacts with a solution of Aluminium Chloride. Solution means in water = (aq)

Step 1. Determine the symbol and charge of each ion (the numerals in () represent the ion’s charge) but write the cation (+ ions) before the non-metal anion(s) (- ions) except for substances with acetate.

Step 2. To write a chemical formula, write ONE of each ion & balance the ion charges so the total is 0 by writing the required coefficient to the bottom right of the ion. For multiples of an atom group, use ( ).
eg. Al3+Cl-, Charge number of Al is a 3 and the charge number of Cl is a 1 so Al1Cl3 but write it as AlCl3
eg. Pb2+NO3- . Charge number on Pb is a 2, and NO3 is only a 1 so Pb1(NO3)2 but write it as Pb(NO3)2.

Balancing equations

Use this simulation to learn how to do this When you click on this image a java file is downloaded - it may take a while (maybe even 120 seconds) depending on the speed of your internet link. Its well worth the wait.
