If it turns red it is an acid.
If it turns blue it is a base.
A buffer solution contains a weak acid and its conjugate base, which helps resist changes in pH when small amounts of acid or base are added. Therefore, a buffer solution contains both acid and base components.
A solution of a base contains hydroxide (OH-) ions, while a solution of an acid contains hydronium (H3O+) ions. Bases typically feel slippery and taste bitter, while acids tend to taste sour.
Whether or not it's an acid or a base
An acid or base is never a single element, it is a solution, and a solution that contains H+ OR OH- in it, so oxygen is neither an acid nor base.

A solution made out of carrot is slightly acidic as it contains vitamins.
Vinegar contains acetic acid, so it is an acidic solution.
The quantity of hydrogen ions in a solution indicates whether the solution is an acid or a base.
Janola is a brand of household cleaning products that contains bleach, making it an alkaline solution.
A buffered solution is made up of a weak acid and its conjugate base (or a weak base and its conjugate acid). These components work together to maintain the pH of the solution by resisting changes in acidity or basicity when small amounts of acids or bases are added.
