Conductivity Lab Questions

Front

What is conductivity?

Back

Conductivity is the ability of a substance to conduct electric current, typically measured in siemens per meter (S/m).

Front

What is the conductivity of solid salt?

Back

Low conductivity, close to zero.

Front

What is the conductivity of a 1.0 M NaCl solution?

Back

Very high conductivity, over 4,000.

Front

What is the conductivity of a 0.10 M NaCl solution?

Back

Very high conductivity, over 4,000.

Front

Why does NaCl have high conductivity in solution?

Back

Dissolved salt, NaCl, has mobile ions that can conduct electricity.

Front

What are mobile ions?

Back

Mobile ions are charged particles that can move freely in a solution, allowing for the conduction of electricity.

Front

What is the difference between ionic and covalent compounds in terms of conductivity?

Back

Ionic compounds conduct electricity when dissolved in water due to mobile ions, while covalent compounds generally do not.

Front

What happens to the conductivity of NaCl when it dissolves in water?

Back

The conductivity increases due to the formation of mobile ions.

Front

What is the role of water in the conductivity of ionic compounds?

Back

Water acts as a solvent that separates the ions in ionic compounds, allowing them to move freely and conduct electricity.

Front

What is the significance of measuring conductivity in a lab?

Back

Measuring conductivity helps determine the concentration of ions in a solution and the ability of a substance to conduct electricity.
