Acids and bases are two specific types of chemicals.

Whether an element is an acid or base depends on the type of ions present in it. If it has so many hydrogen ions, then it is an acid. If it has so many hydroxide ions, then it is a base.

Scientists use a scale called a pH scale to check how acidic or basic a liquid is? The pH scale is a chemical detector for hydronium and hydrogen ions.
