Review: Dilution M1V1 = M2V2

What does M1 represent?

M1 is the initial molarity (concentration) of the solution before dilution.

Define V1 in the dilution formula.

V1 is the initial volume of the solution before it is diluted.

What is M2 in M1V1 = M2V2?

M2 is the final molarity (concentration) of the solution after dilution.

Identify V2 in the dilution formula.

V2 is the final volume of the solution after dilution.

True or false: Dilution increases the concentration.

False, because dilution decreases the concentration.

Fill in the blank: Dilution is the process of _____ a solution.

adding solvent to reduce concentration.

Difference between M1 and M2?

M1 is the initial concentration; M2 is the final concentration after dilution.

What happens to V1 during dilution?

V1 decreases as more solvent is added to achieve V2.

True or false: V1 equals V2 when no solvent is added.

True, because there is no change in volume.

How is the dilution formula derived?

From the conservation of moles, where moles remain constant before and after dilution.

How can you find M2 if you know M1, V1, and V2?

Use the formula: $\displaystyle M2 = \\frac{M1 \cdot V1}{V2}$.

What is the unit for molarity?

Molarity is expressed in moles per liter (mol/L).

What type of solutions can be diluted?

Any solution, including acids, bases, and salts can be diluted.

What does a lower M2 indicate?

A lower M2 indicates a more diluted solution compared to M1.

True or false: Dilution is an irreversible process.

False, because it can be reversed by evaporating the solvent.

What does the term 'concentration' refer to?

Concentration refers to the amount of solute in a given volume of solution.

List factors that affect dilution.

- Amount of solvent added - Initial concentration - Final desired concentration
