Revision Questions on Molarity, Dilutions, and Solution Preparation

Flashcards covering key concepts related to molarity, dilutions, and solution preparation.

Molarity (M)

The number of moles of solute divided by the volume of solution in liters.

Dilution

The process of decreasing the concentration of a solute in a solution.

Stock Solution

A concentrated solution that can be diluted to a lower concentration for actual use.

% Solution

A way to express the concentration of a solution as a percentage of solute per total volume.

Molecular Weight

The mass of one mole of a substance, typically expressed in grams per mole.

EDTA

Ethylenediaminetetraacetic acid, a chemical used in chelation therapy, as well as in biochemical applications.

CaCl2

Calcium chloride, an ionic compound that is highly soluble in water and used in various applications.

Glucose

A simple sugar that is an important energy source in living organisms and is also a component of many carbohydrates.

Buffer

A solution that resists changes in pH when small amounts of acid or base are added.

Final Concentration

The concentration of a solute in a solution after a dilution process or after additional solute has been added.

Volume

The amount of space that a substance occupies, often measured in liters (L), milliliters (mL), or microliters (µL).

Solution Preparation

The method of mixing a solute with a solvent to create a solution of desired concentration.
