Properties of Ionic and Covalent Compounds

Question 1

Short answer

Which compound will you recommend to Ceramic Artisans? Support your answer with data.

Question 2

Short answer

Group the substances into two groups according to their properties.

Question 3

Short answer

List the properties of the two different groups that you created in number 2 (include solubility in both water and alcohol, conductivity in water and melting point).

Group 4

Ionic compounds contain a metal. Covalent compounds do not contain metals. Identify each compound as ionic vs covalent (check the materials section for formulas):

Question 4a

Short answer

Salicylic acid:

Question 4b

Short answer

Sodium carbonate:

Question 4c

Short answer

Sodium chloride:

Question 4d

Short answer

Sucrose:

Question 5

Short answer

Now that you know which substances are ionic and which are covalent, based on your collected data, write a statement to summarize the properties of ionic compounds and another statement to summarize the properties of covalent compounds.

Question 6

Short answer

Water is a polar solvent. Alcohol is nonpolar. Polar substances dissolve in polar solvents and nonpolar substances dissolve in nonpolar solvents. Based on your data of which covalent substance dissolved in water, which covalent compound is polar and which is nonpolar? How do you know?
