Changes in Matter and Chemicals

Science

Forms hydrogen ions when dissolved in water

Acid

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

A compound that changes color when exposed to an acid or a base, like litmus paper

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.

The strength of an acid

Acidity

The strength of an acid. Acidity. Acidity is a measure of how easily an acid donates protons H ions in a solution.

The strength of a base

Alkalinity

The strength of a base. Alkalinity. Alkalinity measures how well a substance can neutralize acids.

Forms hydroxide ions when dissolved in water

Base

Forms hydroxide ions when dissolved in water. Base. A base is a substance that can accept hydrogen ions and usually forms hydroxide ions in solution, making the solution less acidic.

Chemical change explained in an easy to understand way.

the process where substances change into different substances through the breaking of chemical bonds

Chemical reaction explained in an easy to understand way.

a combination of substances that keep their individual properties

Mixture explained in an easy to understand way.

The reaction between an acid and a base, it produces a salt and water

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, creating water and a salt.

The scale of how basic or acidic a solution is based on hydrogen ion concentration

The scale of how basic or acidic a solution is based on hydrogen ion concentration. pH. pH measures how acidic or basic a solution is, with lower values being acidic and higher values being basic.

a change in size, shape, or state but not in identity

Physical change explained in an easy to understand way.

A new substance formed by a chemical reaction

Product

A new substance formed by a chemical reaction product. In science, a product is the end result of a chemical reaction.

A substance that is changed in a chemical reaction

Reactant

A substance that is changed in a chemical reaction. Reactant. A reactant is a starting material in a chemical reaction that undergoes change to form new substances.

a measure of how much solute will dissolve in a solvent

Solubility explained in an easy to understand way.

a mixture of evenly distributed substances

Solution explained in an easy to understand way.
