Describe the ph scale. What do the numbers represent in term of H+ and OH-

pH is the measure of acidity of a substance based on the hydrogen ion concentration. For each number increase on the pH scale, hydrogen ion concentration increases by a factor of 10. All bodily fluids aren't at the same pH but they all have a specific pH at which they must remain. Stomach juice is an acid so pH is below 7 but blood is relatively neutral( pH between 7.45 and 7.55). If blood or any other bodily fluid is not at the correct pH, the body cannot function and it could lead to death.

A PH scale measures the acidic(H+) or basic(OH-) nature of a substance. This scale ranges from 0 to 14.

Pure water has a neutral nature and therefore has a PH of 7.

Any substance with a PH less than 7 is considered acidic (contains H+ ions). This can also be used to determine how acidic the substance is. For instance, a substance with a PH of 1 is considered more acidic than that with a PH of 6 (that is, it has more H+ ions)

Any substance with a PH greater than 7 is considered basic (contains OH- ions). This can also be used to determine how acidic the substance is. For instance, a substance with a PH of 14 is considered more basic than that with a PH of 8 (that is, it has more OH- ions)
