What I think is that … WebbThis gives us a \(pH\) of water equal to 7. The neutral value of the \(pH\) depends on the temperature – being lower than 7 if the temperature increases. A solution with a \(pH\) less than 7 is considered acidic; a solution with a \(pH\) greater than 7 is considered basic, or alkaline. \(pH\) ordinarily ranges between 0 and 14.

WebbAt a pH of 7, this decreases to 0.0000001 M. At a pH of 14, there is only 0.00000000000001 M H+. pH stands for the “power of hydrogen” ³. The numerical value of pH is determined by the molar concentration of hydrogen ions (H+) ³. This is done by taking the negative logarithm of the H+ concentration (-log (H+)).
