Algebra decides what will be the product and what will be the substrate! If you are an experienced chemist you will easily find the mistake in the mixed equation thanks to your chemical knowledge because the example is simple. But the calculator still works! Following the methodology described you will find that the value of some variables will be negative so they should be placed on the opposite side of the equation. If one did not notice the mistake one could not find the solution by means of the classical approach. What would happen if we mistakenly mixed it up a bit?
To solve this system is to find the value of variables a, b, c which are the desired coefficients. With mathematics in mind you can write such a simple equation with variables a, b, c denoting the coefficients to be found:Īll you have to do is balance the quantity for each element on the left and the right side of the equation. Use the calculator with the explanation box checked to see the output. To see how the program finds the solution let`s start from a simple example.Īll the examples can be cut and pasted into the calculator That students will find it very useful in determining the To prove that this algebraic technique works. It was a real shock when I realized the power of It provides better solutions than chemistry itself! SuchĪn idea might seem a bit strange for a chemist. Mathematics provides a general way to find reaction coefficients.
Luckily it turns out that oxidation numbers and half-reaction are unnecessary! Another method exists that uses algebra to find the In some cases however it is hard to use this method because oxidation numbers cannot be unequivocally attributed. The classical approach uses oxidation numbers and many chemists cannot imagine any way to find the solution other than balancing half-reactions for the process. Finding coefficients for chemical reactions is often complicated, especially in the case of redox processes.
