The compound that produce the bright light in the conductance apparatus should be identified. Concept Introduction: Conductivity of electricity is a physical property which is typical of species when dissolved in solution, typically, in an aqueous solution. If the material dissolves properly in water, and conduces electricity, then this is said to be a strong electrolyte. A material which dissolves and only conduces a small amount, will be considered a weak electrolyte. A material which will not conduct electricity at all is considered a nonelectrolyte. Note that sucrose is not even an electrolyte, so ignore it, as it will not conduct electricity.

Solution Summary: The author explains that the compound that produce the bright light in the conductance apparatus should be identified.
6-17. A 0.3396-g sample that assayed 96.4% Na,SO4 re-
quired 37.70 mL of a barium chloride solution.
Reaction:
Ba2+ + SO- → BaSO,(s)
Calculate the analytical molarity of BaCl, in the so-
lution.
(a) What is the percentage concentration of a 1:10,000 solution of epinephrine HCl (MW 219.20)?
(b) If 50 mL of this solution was prepared, what would be the molarity (M)? (c) What is the milligram per deciliter concentration?
