P Rousseau Posted January 23, 2008 Share Posted January 23, 2008 I have two questions regarding charge balancing (mostly considering REACT). Firstly, why is charge balance reported in Faradays. I can understand that it is calculated as such from the numerical solution, but it seems impractical as a measure of the ionic balance. Is there any particular reason why it is reported this way, instead of as a percentage difference? The variable significance of the charge difference with changing ionic strength is of particular interest in this case. Secondly, what is the effect of turning off the charge balance option. I have dealt with a few solutions lately that are difficult to solve in terms of charge balance, as the likely ions result in an unstable model if allowed to act as the charge balancing species. In the end it required iterative adjustment of the alkalinity (the only easily questionable variable that could be manipulated in good concience) to achieve a reasonable charge balance. I hope someone might be able to provide a bit more insight than I seem to be able to find in the literature. Quote Link to comment Share on other sites More sharing options...
