Lecture on Solubility

Overview

• Presenter: Robert Smith
• Institution: New River Community College
• Topic: Solubility and classification of compounds as soluble or insoluble
• Method: Use of a solubility table similar to the one in textbooks

Key Compounds Discussed

Silver Chloride (AgCl)

• Table Reference: Halides section
• Observation: Chloride suggests solubility
• Exception: Ag+ (Silver) makes it insoluble

Lithium Carbonate (Li2CO3)

• Table Reference:
  • Lithium: Found under Group 1 ions with no exceptions
  • Carbonate: Normally insoluble
• Exceptions:
  • Soluble when combined with Group 1 ions or ammonium
• Conclusion: Soluble

Lead Sulfate (PbSO4)

• Table Reference: Sulfates section
• Observation: Sulfate suggests solubility
• Exception: Pb2+ (Lead) attached to sulfate makes it insoluble
• Conclusion: Insoluble

Summary

• The solubility of compounds can be determined using a reference table.
• It is important to check for exceptions on the table that might alter the general solubility rule.
• Examples demonstrated include silver chloride (insoluble), lithium carbonate (soluble), and lead sulfate (insoluble).
