instead of saying that the concentration of hydrogen ion in pure water is 1.00 x 10−7, it is customary to say that the pH of pure water is 7 Linus Pauling also : the condition represented by such a number compare pk More from Merriam-Webster on pH Britannica.com: Encyclopedia article...
The meaning of PHREATOPHYTE is a deep-rooted plant that obtains its water from the water table or the layer of soil just above it.
pH is usually to measure acidic or basic water is. pH is a measure of the relative amount of free hydrogen and hydroxyl ions in water. There are 0-14 range to be measure which is 7 is for neutral while pH which less that 7 is acidity and the pH which is greater than 7 is alkali...
Acids and bases are two opposing extremes, so mixing acid and base of equal extremity makes the solution even out and become neutral, just like mixing hot and cold water. Although some substances differ in acidity by a unit of measurement, their actual difference is about tenfold. Meaning the...
Adjusting pH in Water Pure or distilled water has a pH level of 7, which means it is neutral. If you want to increase the pH of water, you must add an alkaline substance, such as baking powder, to it. If you want to decrease the pH of water, you add an acidic substance, such ...
Mathematical definition of pH is a little less intuitive but more useful in general. It states that the pH equals the negative logarithmic value of the concentration of hydrogen ion (H+) pH = -log [H+] A water source ‘s pH value is a function of its acidity, or alkalinity. The pH ...

refers to the negative logarithm of H+ion concentration. The term pH is derived from the German word "potenz" which means "power," and H is derived from the chemical symbol of hydrogen. So, pH stands for 'power of hydrogen' or the meaning of pH is also justified as the power of ...
The meaning of CARYOPHANALES is a small order of filamentous bacteria that occur in water, decaying organic matter, and the alimentary canal and have in general the characteristics of members of the genus Caryophanon.
Not All Liquids Have a pH Value A pH value only has meaning in anaqueous solution(in water). Many chemicals, includingliquids, do not havepH values. If there is no water, there is no pH. For example, there is no pH value forvegetable oil, gasoline, or pure alcohol. IUPAC Definition ...
