Properties of Solids

Question 1

Ionic Solids

Answer 1

• High melting/boiling point
• Dissolves well in polar solvents
• Dissolves poorly in non-polar solvents
• Poor conductor when solid
• Great conductor when liquid or dissolved

Question 2

Molecular Solids

Answer 2

• Low MP/BP due to weak IMFs
• When polar, dissolves in polar
• When non-polar, dissolves in non-polar
• Always a poor conductor

Question 3

Network Covalent Solids

Answer 3

• Very high MP/BP
• Dissolves poorly
• Poor conductors

Question 4

Metallic Solids

Answer 4

• Mostly high MP/BP
• Doesn’t dissolve well
• Excellent conductors
