Where Do Acids Fall On The Ph Scale. The value of pH scale ranges from 0 to 14. The pH inside human cells 68 and the pH of blood 74 are both very close to neutral.
Thus small changes in pH represent large changes in the concentrations of hydrogen ions. A decrease in pH values from 50 to 40 means that the acidity is 10 times greater. Acidic substances have pH values ranging from 1 to 7 1 being the most acidic point on the pH scale and alkaline or basic substances have pH values ranging from 7 to 14.
A pH of 7 is neutral on the scale greater than 7 is a base and less than 7 is an acid.
Solutions having the value of pH equal to 0 are known to be strongly acidic solutions. A lower pH means something is more acidic also known as a stronger acid. The particular salt made. 12 points Label where acids bases and neutral substances would fall on the pH scale.
