Question 1.
What is conductivity?
Show hintHide hint
Think about what allows electricity to flow.
Question 2.
What is molar conductivity?
Show hintHide hint
It tells you conductivity per mole.
3Question 3.
What is the primary function of conductivity cells?
- To measure temperature
- To measure conductivity
- To measure pressure
Show hintHide hint
Think about what you need to measure electrical flow.
4Question 4.
True or False: Higher concentration always means higher conductivity.
- True
- False
Show hintHide hint
Consider exceptions like weak acids.
Question 5.
A conductivity cell has a cell constant of 1.5 cm⁻¹. If a 0.2 M KCl solution has a resistance of 500 Ω, calculate its conductivity and molar conductivity.
Show hintHide hint
Use the relationships and formulas provided to derive the answers.
Question 6.
Discuss the differences in behavior of strong versus weak electrolytes concerning conductivity when diluted.
Show hintHide hint
Think about why stronger electrolytes exhibit such distinct behaviors when introducing water.
