Overview

Solutions are homogeneous mixtures that play a crucial role in chemistry and our daily lives. From the salt water in our oceans to the sugar in our tea, solutions are everywhere. This chapter explores the fundamental concepts of solutions, their properties, and how these properties depend on the con

Key Concepts

A solution consists of solute (substance

A solution consists of solute (substance being dissolved) and solvent (substance doing the dissolving). The solvent maintains the same physical state

Five main ways to express concentration

Five main ways to express concentration: Molarity (M) = moles of solute/liters of solution; Molality (m) = moles of solute/kg of solvent; Normality (N

The mole fraction of a gas

The mole fraction of a gas dissolved in a solvent is directly proportional to its partial pressure: x = Kp. Valid for gases that don't react with solv

For volatile liquid mixtures

For volatile liquid mixtures: PA = P°A × XA, where PA is partial vapor pressure, P°A is vapor pressure of pure liquid, and XA is mole fraction. For no

Ideal solutions obey Raoult's law completely

Ideal solutions obey Raoult's law completely with no heat or volume change on mixing. Non-ideal solutions show positive deviation (weaker A-B interact
