What are solutions?

Solutions are homogenous mixtures composed of solutes and solvents.

What is a solute?

The minority component of a solution.

What is a solvent?

The majority component of a solution, often water in aqueous solutions.

What is molarity (M)?

Molarity (M) is a unit of concentration defined as the number of moles of solute per liter of solution.

What is dilution?

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

What is an Acid-Base Reaction?

A reaction where an acid produces H+ ions and a base produces OH- ions.

What is a Net Ionic Equation?

A Net Ionic Equation shows only the species that actually participate in a reaction, omitting spectator ions.

What is a precipitate?

A solid that forms and settles out of a liquid mixture during a chemical reaction.

What is an Oxidation-Reduction (Redox) Reaction?

It is a reaction involving the transfer of electrons where oxidation (loss of electrons) and reduction (gain of electrons) occur.

What is Mass Percentage?

Mass Percentage is a measure of concentration calculated as the mass of solute divided by the total mass of solution, multiplied by 100.

What is Parts per Million (ppm)?

Parts per Million (ppm) is a unit of measurement used to describe the concentration of a substance in a solution, equivalent to 1 mg of solute in 1 L of solution.
