Solution Concentration and Dilutions

These flashcards cover key concepts related to concentration units, stoichiometry, electrolytes, and solutions, aiding in exam preparation.

Molarity

A concentration unit defined as the number of moles of solute per liter of solution.

Stoichiometry

The calculation of reactants and products in chemical reactions, often involving molarity in solutions.

Parts per million (ppm)

A concentration unit equivalent to 1 milligram of solute per liter of solution.

Electrolyte

A solute that produces ions in solution, allowing it to conduct electricity.

Weak Electrolytes

Substances that partially dissociate into ions in solution, resulting in slight conductivity.

Strong Electrolytes

Substances that fully dissociate into ions in solution, conducting electricity efficiently.

Molarity equation

M = moles of solute / liters of solution.

Dilution

The process of reducing the concentration of a solution by adding more solvent.

Concentration

Describes the amount of solute dissolved in a given amount of solvent or solution.

Homogeneous Mixture

A mixture in which the components are uniformly distributed at the molecular or atomic level.
