Conductivity (April 14,2010)

In the beginning of class, we checked the conductivity of distilled water by itself, which turned out to be 0. However, when we add salt to it, the conductivity immediately got higher. Afterwards, we decided to see what the conductivity of tap water is, which not surprisingly turned out to be 0 as well. But when we added salt to it, once again, it quickly got higher. After this mini experiment, we learned how to tell whether solutions could be conductive, or non-conductive.

Electrical conductivity in solutions requires charged ions to be present.
