Study Notes
Conductivity and Solution Composition
- Presence of bubbles in the solution can lead to errors in measuring conductivity values.
- Accurate conductivity values require removal of bubbles before starting the experiment.
- Increasing the number of molecules in the solution increases the presence of ions, resulting in higher conductivity and diffusivity values.
- As concentration increases, the number of molecules in the solution also increases.
Factors Affecting Conductivity
- Conductivity depends on the presence of ions in the solution.
- Mixing substances like NaCl with distilled water before the experiment can affect conductivity values.
Note: The sentence about Pepperstone Financial Services (DIFC) Limited is irrelevant to the topic of conductivity and solution composition, so it was not included in the study notes.
