In this lecture you will learn about Solutions, Henry's Law, and Concentration Equations. First you will review Types of Solutions such as Homogeneous Mixtures and Solid Solutions. Next will be Saturation Solubility where you will delve into Solubility Dependencies. Henry's Law as well as values for Henry's Law Constant will be investigated before moving onto Solution Concentration Expressions such as Percentage by Mass, Molarity, and Molality. Next you will learn about Dilution of Solutions as well as Effects of Temperature on Solubility with cases of Gases in Liquids as well as Solids in Liquids. Lastly you have a Qualitative Introduction to Entropy along with Temperature Effects of Enthalpy and Entropy.
every phase in every other; solutions in liquids most important
solubility: no more solute will dissolve in solvent; an equilibrium
Law for gases in liquids: s = KP; effects shown in carbonated
liquids; divers and the bends
expressions: % by mass; molarity = mol. solute/L soln.; molality =
mol. solute/ kg solvent
examples of interconverting solubility expressions for particular
MV = const
effects: gases, always lower S as T increases; solids varying
means mixed-upness, chaos; temperature effects on S can be explained
by enthalpy and entropy effects
Solutions, Henry's Law, Concentration Equations
