Unit 6 – Conductivity of Substances and Solutions Lab

(Lab Data and Notes Only)

Lab Questions/Notes:

1. a) Classify all the COMPOUNDS that you made into solutions into the category of ELECTROLYTE or

NONELECTROLYTE.

I WILL NOT CLASSIFY ______________ AND _____________ BECAUSE THEY ARE ELEMENTS and CONDUCTORS.

Electrolytes

Nonelectrolytes

(Write the NAME and the FORMULA)

b) Did any of these compounds conduct electricity when they were in solid form? ______________

c) Using your observations, define and answer the following:

electrolyte:

nonelectrolyte:

conductor:

d. Look at the names and formulas of all the compounds and answer the following. Use your Periodic Tables to

determine if the elements are metals or nonmetals.

* ALL ELECTROLYTES begin with metals/nonmetals (circle one), with the exception of one compound which is:

_________________________________

* ALL NONELECTROLYTES are made up of ALL metals/nonmetals (circle one).

2. There are 2 types of compounds:

MOLECULAR COMPOUNDS: DO NOT conduct electricity either as a solid or a liquid (nonelectrolytes).

Molecular compounds are made up of ALL _______________ (look above).

*WHY? These compounds, typically, DO NOT CONDUCT ELECTRICITY because they are made

up of neutral aggregates of atoms called molecules.
