* pH Scale: The pH scale measures the acidity or alkalinity of a solution. It ranges from 0 to 14.
* 0-6.9: Acidic
* 7: Neutral (like pure water)
* 7.1-14: Alkaline (or basic)
* Acids: Acids release hydrogen ions (H+) into solution. The higher the concentration of H+ ions, the stronger the acid and the lower the pH.
* Water: Pure water has a pH of 7 because it has an equal concentration of H+ and OH- (hydroxide) ions.
In summary: Acids have a higher concentration of H+ ions, making them more acidic and giving them a lower pH than water.
