Document Summary

We have just seen that, when an ionic compound dissolves in water, the resulting solution contains, not the intact ionic compounds itself , but its component ions dissolved in water. However, not all ionic compounds dissolve in water. In a general sense, a compound is termed soluble if it dissolves, and insoluble if it does not. Additionally, if a solution can dissolve no more solute it is saturated, and substances that dissolve in each other in all proportions are called miscible. Aquation: when water is used to dissolve ions. All fluorides (f-) are soluble except mg2+ , ca2+ All chlorides (cl-) are soluble except ag+ hg2. All bromides and iodides are soluble except ag+, hg2. All sulfides (s2-) are insoluble except groups i and ii elements and nh4. 2-) are soluble except ag+, ba2+, ca2+, hg2. Like dissolves like; polar solvents dissolve polar solutes and non-polar solvents dissolve non-polar solutes.
