pH: ACIDS VERSUS BASES

Measure of Hydrogen Ions (H+) in solution: The more Hydrogen Ions (H+) there are the more acidic a solution is.

Water

Where do Hydrogen Ions (H+) come from? Well, it's all part of water really...

Sometimes other chemicals are present that are dissolved by water. The pieces that result may contain an Hydrogen Ion (H+) or Hydroxyl Ion (OH-). This will change the pH.

Acids

Acids add Hydrogen Ions (H+) to solutions.

Bases

Bases add Hydroxyl Ion (OH-) to solutions.

Anything that's too acidic or too basic will degrade organic matter. Tissues are destroyed, cells will die or at least not function properly.
