Flashcards: Aqueous Solutions and Concentrations — 11 cards

What is a solution in chemistry?

A homogeneous mixture of solutes dissolved in a solvent.

What distinguishes a solute from a solvent in a solution?

The solute is the dissolved species and often minor, the solvent is the major species.

What is mass concentration in a solution?

Mass concentration is the mass of solute dissolved per litre of solution.

What formula relates mass concentration, solute mass, and solution volume?

$C_m=\frac{m}{V}$ where $m$ is solute mass and $V$ is solution volume.

Solution Composition Notation

Solute: minor; solvent: major component.

Mass Concentration Formula

$C_m = \frac{m}{V}$, solute mass per litre.

Saturated Solution

Maximum solute dissolved; no more dissolves.

Solubility (s)

Max mass of solute per volume in solvent.

Mass Density Formula

$\rho=\frac{m_{solution}}{V}$; mass of solution per volume.

Mass Concentration vs Density

Concentration: solute; density: entire solution.

Dilution Factor (F)

Ratio of final to initial volume, $F=\frac{V_f}{V_0}$.
