Balancing Equations: Crystal Clear Chemistry

Practice balancing hundreds of chemical equations of varying types, including ionic equations, redox equations and half equations. Begin with the basics by practicing balancing chemical equations containing molecular and compound formulae. You can play at a basic or advanced level to suit your level of chemistry.

Once you’ve mastered compound and molecular equations, then move to the more challenging skills involved in balancing ions and electrons in ionic, redox and half equations. Again, chose whether to start with basic or advanced level questions. Once you have mastered all the variety of questions, you will have truly mastered balancing equations.

On every level of gameplay an unbalanced chemical equation is given; simply enter the number of each species required to balance it and click submit to check your answer. If a submitted answer is incorrect, guidance is given on how to work out the correct answer, thereby helping you improve your skill at balancing equations.
