Question 1.
What is conductance?
Show hintHide hint
Remember, conductance is related to resistance!
Question 2.
What formula represents specific conductance?
Show hintHide hint
Think about how distance and area play a role here.
3Question 3.
What is the formula for specific conductance?
- A) κ = G / (l × A)
- B) κ = G × (l / A)
- C) κ = G × l / A
Show hintHide hint
Pay attention to the positioning of the variables in the formula.
4Question 4.
Molar conductance increases sharply with dilution for:
- True
- False
Show hintHide hint
Think about the difference between strong and weak electrolytes.
Question 5.
A solution has a conductance of 0.05 S. If the area of electrodes is 1 cm², and the distance between them is 0.5 cm, calculate the specific conductance.
Show hintHide hint
Don’t forget to consider units carefully while calculating.
Question 6.
If the molar conductance of acetic acid is found to be lower than that of sodium chloride, what could be a probable reason for this observation?
Show hintHide hint
