What is the primary purpose of using voltammetry in chemical analysis?

To measure mass changes in chemical reactions.

To determine the concentration of an analyte.

To separate components of a mixture.

To generate ions from the analyte.

What is the fundamental difference between coulometry and electrogravimetry?

Coulometry measures the total charge required for a reaction, while electrogravimetry measures the change in mass.

Coulometry uses a constant potential, while electrogravimetry uses a constant current.

Coulometry is used for qualitative analysis, while electrogravimetry is used for quantitative analysis.

Coulometry requires the deposition of the reaction product on the electrode, while electrogravimetry does not.

What is the primary purpose of using triangular wave voltammetry (TWV) compared to other voltammetric methods?

To generate multiple peaks in the voltammogram.

To reduce interference in the electrochemical reaction.

To measure the total charge during electrochemical reactions.

To increase the sensitivity of current measurements.

What is the main difference between pulse voltammetry and differential pulse voltammetry?

Pulse voltammetry uses a periodic potential pulse, while differential pulse voltammetry uses a constant potential.

Pulse voltammetry measures current only at the beginning of the pulse, while differential pulse voltammetry measures current at the end of the pulse.

Pulse voltammetry applies pulses at irregular intervals, while differential pulse voltammetry uses regular intervals.

Pulse voltammetry is used for qualitative analysis, while differential pulse voltammetry is used for quantitative analysis.

What is the primary advantage of ion-selective electrodes over inert-indicator electrodes in potentiometry?

Ion-selective electrodes provide faster results.

Ion-selective electrodes respond to all ions in the solution.

Ion-selective electrodes can selectively respond to specific ions.

Ion-selective electrodes are more durable.
