Question

In contextto voltametry, which ofthe following statement is false?

• A. Technique can be used to analyse organic compounds containing carbonyl groups
• B. Organic solvents cannot be used as aqueous organic mixture in this technique
• C. Immuno sensors are available in voltametry
• D. Triangular waveform is used for excitation of solution in cyclic voltametry

Answer 1

The Correct Option is B

In voltammetry, various statements describe its applications, functionality, and operating principles. Let's analyze each option to determine the false statement:

1. Technique can be used to analyse organic compounds containing carbonyl groups: Voltammetry is indeed a versatile technique used for analyzing organic compounds, including those with carbonyl groups. This statement is correct.
2. Organic solvents cannot be used as aqueous organic mixture in this technique: This statement is false. In certain voltammetric techniques, organic solvents can be mixed with aqueous solutions to analyze specific compounds. Therefore, the correct answer is that this statement is false.
3. Immuno sensors are available in voltammetry: Immunosensors, which combine electrochemical detection with biological recognition, are indeed utilized in voltammetry to detect various substances. This statement is correct.
4. Triangular waveform is used for excitation of solution in cyclic voltammetry: In cyclic voltammetry, the potential of the working electrode is cycled by applying a triangular waveform. Hence, this statement is correct.

The false statement is: Organic solvents cannot be used as aqueous organic mixture in this technique. This indicates that contrary to the statement, organic solvents can be mixed with aqueous solutions in voltammetric techniques.
