Acids, Bases and Solutions

Acid

Forms hydrogen ions when dissolved in water. Acid. An acid is a substance that releases hydrogen ions into a solution, making it acidic.

Acid base indicator

A compound that changes color when exposed to an acid or a base, like litmus paper. Acid base indicator. An acid base indicator is a substance that helps identify whether a solution is acidic or basic by changing color.

Colloid

A mixture in which the particles never settle. Colloid. A colloid is a type of mixture where tiny particles are dispersed evenly throughout without settling to the bottom.

Dilute

A mixture with very little dissolved solute. Dilute. In Science, "dilute" means a solution has a small amount of solute compared to the amount of solvent.

Neutralization

The reaction between an acid and a base, it produces a salt and water. Neutralization. Neutralization is when an acid and a base react to cancel each other out, forming water and a salt.

PH

The scale of how basic or acidic a solution is based on hydrogen ion concentration. pH. pH measures how acidic or basic a substance is, on a scale from 0 very acidic to 14 very basic.

Saturated solution

A solution that contains the maximum amount of dissolved solute at a given temperature. Saturated solution. A saturated solution is one where no more solute can dissolve in the liquid at that specific temperature.

Solute

The substance that is dissolved to form a solution. Solute. A solute is the material that gets dissolved in a liquid to make a solution.

Solution

A mixture of evenly distributed substances. Solution. A solution is a homogeneous mixture where substances are completely dissolved in a liquid.

Solvent

The substance in which another substance is dissolved. Solvent. A solvent is a liquid that dissolves a solid, liquid, or gas to form a solution.

Supersaturated solution

A solution with more dissolved solute at a given temperature, than a saturated solution. Supersaturated solution. A supersaturated solution contains more dissolved material than it normally would hold at a given temperature, and is unstable.

Suspension

A mixture in which the solid particles are large enough to be seen. Suspension. In science, a suspension is a type of mixture where small solid particles are dispersed throughout a liquid but are not dissolved, allowing them to eventually settle.

Unsaturated solution

A solution that can dissolve more solute at a given temperature. Unsaturated solution. An unsaturated solution is a mixture that has the capacity to dissolve more of a substance.
