Types of Mixtures and pH

This set of flashcards reviews vocabulary related to types of mixtures and the pH scale as covered in the lecture.

Mist

A mixture of tiny droplets of water and air that obscures view.

Solution

A clear mixture of a solid, liquid, or gas in a liquid where the solute is finely divided.

Suspension

A turbid mixture of a solid in a liquid, where particles are too large to let light through.

Emulsion

A turbid mixture of two liquids where one liquid is dispersed in another.

Emulsifier

An auxiliary substance that helps keep an emulsion mixed.

pH

A scale that indicates the acidity or alkalinity of a solution, ranging from 0 to 14.

Acidic Solution

A solution with a pH less than 7, indicating higher concentration of hydrogen ions.

Alkaline Solution

A solution with a pH greater than 7, indicating higher concentration of hydroxide ions.

Neutral Solution

A solution with a pH of approximately 7, indicating no effect from acids or bases.

Dilution

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