Negative pH definition of Negative pH by Medical dictionary

WebThe pH scale is logarithmic and shows the solution’s concentration of hydrogen ions inversely. More specifically, the pH of the solution is the negative logarithm to the base 10 of its hydrogen ion concentration in moles per litre. The pH scale can be traced to a series of standard solutions whose pH is defined by international agreement. WebAt 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+)). WebSo, in fact, you can't measure negative pH value, meanwhile you can calculate negative pH values.
