Any errors found with straight forward titrations will be the same as for back titrations, the only difference with the back titration is that you have to do some kind of conversion reaction of the substance of interest to a species that can be titrated within the next step. So errors can be found with the way you handle the equipment and reactants, the measuring equipment you have used and just how you do the titration. |

I think more context has to be provided. What equations/procedures are taking place in the back titration? Back titrations have an initial reaction which merely prepares the solution to be titrated in the second reaction. This preparation step may vary depending on the type of compound being evaluated. Hence, the presence of insoluble compounds may have a different effect depending on the initial preparation reaction and hence produces a different error. |
