Which of the following statements is correct?
pH values are logarithmic values of Nitrogen/Nitronium ion concentration.
pH scale was discovered by Soren Sorensen in 1909.
pH value range from 0-14, 0 being the most alkali and 14 being the least alkali.
pH of less than 0 values does not exist.
The pH range is from 0 to 14, with 7.0 being neutral. Anything above 7.0 is alkaline, anything below 7.0 is considered acidic. A healthy blood pH without cancer has acid + alkaline balance almost equal. Actually a healthy body is slightly alkaline measuring approximately 7.4.
