The majority of ionic substances are solids at room temperature. Describe what you would observe if you placed a soluble ionic compound and an insoluble ionic compound in separate beakers of water.


Establish the solubility rules to determine which compound will be soluble and not.

Step 1. Recall the solubility rules:

  • Ionic compounds are usually composed of a nonmetal and a metal. 
  • On the other hand, molecular compounds are composed of exclusively non-metals
  • Note that molecular compounds cannot be analyzed as soluble or insoluble using the solubility rules.
