Balance redox reactions

Posted 9 years ago

Hi.

I wonder if I can balance redox reactions, without adding H+, OH- and H2O to the equation. Can I tell the computer, that it is an acidic or an alkaline solution?

Example:

Balance chemical equation H2O + MnO4^- + SnO2^-2 = MnO2 + SnO3^-2 + OH^-

Thanks!

I'd like to see some details of how you use the Grassmann algebra package to handle such reactions.

P.S. The link to your Mathematica page (http://my.xfinity.com/~djmpark/Mathematica.html) currently is dead!

Presumably you entered exactly that into Wolfram|Alpha. Here is a link to the result I obtained. I guess this was not quite what you wanted, so it would be helpful if you explained in more detail what it is you were hoping to get as result.

Thanks for your reply Daniel.

When you balance a redox reaction, you have to know whether the solution is acidic (H+) or alkaline (OH-). That will determinate if you have to balance the equation with H+ ions or OH- ions. If I just enter the chemical equation:

MnO4^- + SnO2^-2 = MnO2 + SnO3^-2

Then Wolfram does not know how to balance the redox reaction. How can I tell the computer to balance a redox reaction, and at the same time tell it, that the solution is acidic or alkaline in the input field?

Thanks!
