pH scale- (from potential of Hydrogen) the logarithm of the reciprocal of hydrogen-ion concentration in gram atoms per liter; provides a measure on a scale from 0 to 14 of the acidity or alkalinity of a solution (where 7 is neutral and greater than 7 is more basic and less than 7 is...
While his objective was originally geared in furthering research for a beer company, his findings gave the chemical world an alternate and more universal scale that could be used by scientists to view hydrogen ion concentration. The pH scale consists of the numerical range of 0-14. Acids are ...
The meaning of PH is a measure of acidity and alkalinity of a solution that is a number on a scale on which a value of 7 represents neutrality and lower numbers indicate increasing acidity and higher numbers increasing alkalinity and on which each unit o
A new nonlinear immobilized pH gradient (IPG) is proposed as the first dimension for two-dimensional electrophoresis. In comparison to conventional carrier ampholyte techniques, it offers better resolution and greater reproducibility whilst allowing application of higher protein loads. Furthermore, we have...
PH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions. The term, widely used in chemistry, biology, and agronomy, translates the values of the concentration of the hydrogen ion into numbers between 0 and 14. Learn more
This is necessary for pH gradients to be defined in a pH scale relevant to the focusing conditions such that spot positions can be related to amino acid compositions. The data will allow definition of pH scales for the temperature range 10-25掳C and for a pH range covering the major part...

He left to physicians and surgeons the care of drawing conclusions from his great work in biology, and of acting experimentally upon animals allied to man in order to found a rational system of therapeutics. So he preferred to operate upon beings placed low in the animal scale—the frog ...
The meaning of PH is a measure of acidity and alkalinity of a solution that is a number on a scale on which a value of 7 represents neutrality and lower numbers indicate increasing acidity and higher numbers increasing alkalinity and on which each unit o
The pH scale finds its way into many aspects of everyday life as well as into science and industry. It is used in cooking (e.g., reacting baking powder and an acid to make baked goods rise), cocktail design, cleaners, and food preservation. Knowing pH is important when working in pool...
