* Pure distilled water is extremely close to neutral, but not quite. The pH of pure distilled water is very slightly acidic, typically around 6.8 to 7.2.

* The pH scale ranges from 0 to 14.

* A pH of 7 is considered neutral. This means the solution is neither acidic nor basic.

* Acidic solutions have a pH below 7.

* Basic (alkaline) solutions have a pH above 7.

Why is distilled water slightly acidic?

* Carbon dioxide from the air dissolves in water. This creates carbonic acid, which makes the water slightly acidic.

Important Note: Distilled water, while very close to neutral, will rapidly absorb CO2 from the air and become slightly acidic. It's difficult to maintain pure distilled water in a truly neutral state for long.
