Question

You are studying the differences between ionic and covalent compounds. After studying the properties of each type of compound, your teacher has provided this table and asked you to (1) identify the ionic compound(s) and explain your choice(s).

Responses
A Compound B because it has a very high melting point.
B Compounds A, B and C because they are soluble in water.
C Compounds A, B, and C because they are solid at room temperature.
D Compounds A and D because they have relatively high melting points.
E Compounds A and D because the conduct electricity in aqueous solutions.

Answer 1

The correct answer is D. Compounds A and D are the ionic compounds in the table. Ionic compounds typically have high melting points and are solid at room temperature. They also conduct electricity in aqueous solutions. These properties are characteristic of compounds that have ionic bonds, where electrons are transferred from one atom to another to form positive and negative ions.
