Hi,

Have a redox titration assessment tomorrow (think it's quantitative) however I'm really struggling to understand how the equations work, in AS it was easier because they cued you in.

Also could anyone talk me through the steps of carrying out a redox titration? Eg what you have to wash etc

Thanks for any/all help

Basically you can only add H+, e- and H2O to the equation to make it balance. The overall charge of both sides also has to balance. Sometimes you can add hydroxide, but I don't think every exam board does this. Look on Chemguide and it has good explanations of it all.

With the titration, you want to wash everything with distilled water. A bit of distilled water left over in the conical flask doesn't matter, it actually makes you more likely to get accurate results.

Thanks!

I'll check chem guide after I finish getting my head around these calculations
