How to do electrical conductivity tests?

Click For Summary
SUMMARY

This discussion focuses on conducting electrical conductivity tests using various substances, including salt, candle wax, toothpaste, and sand. The participants clarify that an "electrical conductivity tester" likely refers to a Digital Volt Meter (DVM). The proper procedure involves testing the substances in water to determine their conductivity, particularly for soluble materials like salt, while non-soluble materials like wax and sand require different approaches. The conversation emphasizes the importance of understanding the properties of each substance when conducting these tests.

PREREQUISITES
  • Understanding of electrical conductivity principles
  • Familiarity with Digital Volt Meters (DVM)
  • Knowledge of solubility and its impact on conductivity
  • Basic laboratory safety protocols
NEXT STEPS
  • Research the operation and calibration of Digital Volt Meters (DVM)
  • Learn about the solubility of various substances and their effect on electrical conductivity
  • Investigate alternative methods for testing conductivity in non-soluble materials
  • Explore laboratory procedures for conducting electrical conductivity experiments
USEFUL FOR

Students in chemistry or physics courses, educators preparing lab procedures, and anyone interested in practical applications of electrical conductivity testing.

Our teacher gave us a lab, and we have to write a procedure on how to test the electrical conductivity of multiple substances. However, on the materials, all that was written was "electrical conductivity tester", which I'm not sure what it is since we have not learned about it at all, and in the textbook it says "conductivity apparatus".
The things we were given include salt, candle wax, toothpaste and sand.
Should we be putting them into water and then sticking it in, or just by itself?
Thanks!

p.s. In one of the questions, it asked about standing in a puddle with salt or sugar, so I am guessing it is in water, but how would that work for something like wax or sand?

That's probably just a DVM. have you used a DVM in your labs before?
