Chad provides an introductory lesson on Solutions. The lesson begins with a description of the 3 steps of the solution process and the energetics involved. This is then used to explain why some substances mix while others do not. The principle of "like dissolves like" is introduced and a variety of solutions vocabulary terms are defined including miscible, immiscible, saturated, unsaturated, supersaturated, and colloids. The lesson concludes with a discussion on some of the factors affecting the solubility of gases and ionic solids. This includes the affect of temperature and pressure on the solubility of gases including Henry's Law, and the affect of temperature on the solubility of ionic compounds in water.

I've embedded this playlist as a course on my website with all the lessons organized by chapter in a collapsible menu and much of the content from the study guide included on the page. Check this lesson out at [ Ссылка ]
