Study Notes
Measurement of Conductance
- A conductometer is used to measure conductance.
Ohm's Law
- Ohm's law states that the potential difference across a conductor is directly proportional to the current flowing through it.
Effect of Potential Difference on Current
- If the potential difference across a conductor is doubled, the current will also double.
Specific Conductance
- Specific conductance is also known as molar conductivity.
Conductometric Titration
- The principle behind conductometric titration is the measurement of the change in conductance of a solution during a titration reaction.
- The end point in conductometric titration is determined by a sharp change in the conductance graph.
- Ion-selective electrodes are typically used in conductometric titration.
Significance of Sharp Change
- The sharp change observed during conductometric titration indicates the completion of the titration reaction.
Purpose of Conductometry
- The main purpose of conductometry is to measure the ionic concentration of a solution.
Unit of Conductance
- The unit of measurement for conductance is Siemens (S).
Factors Affecting Conductance
- Conductance depends on the concentration of ions, temperature, and the nature of the solvent in a solution.
Conductivity of a Solution
- Ions are responsible for the conductivity of a solution in conductometry.
