Solubility and Ionic Compounds

The video tutorial explains how to use Reference Table F to distinguish between soluble and insoluble compounds. Soluble substances dissociate completely in water, forming aqueous solutions, while insoluble compounds remain mostly solid. Examples include sodium chloride, which is soluble, and lead iodide, which is insoluble. The tutorial also covers the solubility of halides, phosphates, and hydroxides, highlighting exceptions to general rules.
