In this case, we only need to consider the potential that would be needed to start the plating of Fe 2 + , since plating of any iron will interfere with the measurement of cadmium.

Later, as you read through the descriptions of specific gravimetric methods, this survey will help you focus on their similarities instead of their differences. You will find that it is easier to understand a new analytical method when you can see its relationship to other similar methods.

Coulometry measures analyte concentration through exhaustive electrolysis, with two types: controlled-potential and controlled-current. Controlled-potential maintains a constant electrode potential to achieve 100% current efficiency, while controlled-current maintains constant current.

By exhaustive we mean that the analyte is completely oxidized or reduced at the working electrode or that it reacts completely with a reagent generated at the working electrode. There are two forms of coulometry: controlled-potential coulometry, in which we apply a constant potential to the electrochemical cell, and controlled-current coulometry, in which we pass a constant current through the electrochemical cell.

It explains precipitation gravimetry, where a reaction creates a precipitate linked to the analyte, and volatilization gravimetry, where decomposition leads to mass measurements of residue or volatilized products. It also touches on particulate gravimetry for direct analysis of analytes in a separable form.

It discusses methods including direct analysis, where the analyte is weighed directly, and indirect analysis, where the analyte is measured by a change in mass.
