Solubility of Ionic Compounds

Mr. Rootsart explains the solubility of ionic compounds, using a solubility chart to determine whether compounds dissolve in water. He provides examples, such as ammonium sulfide and silver chloride, to illustrate how to use the chart. The video emphasizes the importance of practice and understanding the periodic table to master solubility concepts.

What is the main factor that determines whether an ionic compound is soluble in water?

• The color of the compound

• The size of the ions

• The temperature of the water

• The solubility chart

What does it mean if a compound is labeled as 'aqueous' in a solution?
