In chemistry, pH (/piËËeÉªtÊ/) is a numeric scale used to specify the acidity or basicity of an aqueous solution. It is approximately the negative of the logarithm to base 10 of the molar concentration, measured in units of moles per liter, of hydrogen ions.
What are pH values. why is it important to know pH value of items? The scale that is used for measuring the pH, or hydrogen ion concentration â¦ is from 0 to 14, with 7 being the neutral point. The scale for the concentration of hydrogen ion â¦ s is called the pH value. This stands for potential Hydrogen or strength of the hydrogen. The pH value indicates whether a solution reacts alkaline, neutral, or acid. In a neutral solution, such as pure water, the pH is exactly 7. The pH of an acid solution is less than 7, the pH of an alkaline solution is higher than 7. Thus, an Alkaline Body pH means that the pH of the blood is above 7 with the ideal pH being 7.35. Outside of this range - the body activity is no longer optimal and the metabolism is out of balance.
