Question

Boiling Point Electrical conductivity in aqueous solution Solubility in H2O (grams of solid in 100 grams H2O)

A Low, 65o C Poor 3.0
B High 1600o C Good 36.0

You are given two unknown solutions, A and B. One of the solutions contains water and table salt, and the other contains water and table sugar. Without any testing, using the data table and your knowledge of chemical bonds, you are able to determine which solution contains sugar and which contains salt. Which solution is which?
A) A contains sugar and B contains salt, because salt is ionic and a good conductor of electricity.
B) A contains salt and B contains sugar, because sugar is ionic and is a good conductor of electricity.
C) A contains salt and B contains sugar, because salt is covalent and is poor conductor of electricity.
D) A contains sugar and B contains salt, because sugar is covalent and is a good conductor of electricity.

Answer 1

A) A contains sugar and B contains salt, because salt is ionic and a good conductor of electricity.

Step-by-step explanation:

A contains sugar and B contains salt, because salt is ionic and a good conductor of electricity.. Covalent compounds do not form charged ions in solution, thus they are poor conductors of electricity, while ionic compounds do produce ions in solution and are good conductors. Sugar is a covalent compound, thus it would be a poor conductor in solution.

Answer 2

A) A contains sugar and B contains salt, because salt is ionic and a good conductor of electricity.

Step-by-step explanation:

Because sugar is not a good conductor of electricity
