Five samples of sodium chloride are listed below.
Sample 1: 10 g NaCl in 200 mL of water
Sample 2: 20 g NaCl in 200 mL of water
Sample 3: 30 g NaCl in 400 mL of water
Sample 4: 2.5 g NaCl in 100 mL of water
Sample 5: 6.25 g NaCl in 50 mL of water
List the samples 1 to 5 in order of increasing conductivity. Write a few sentences to
describe how you came to your conclusion.
