Buffer Solution
GFS ChemicalsThe pH of a sample is an indication of its acidity or alkalinity and pH determination is one of the most commonly conducted laboratory measurements. The term pH is defined as the negative logarithm (base 10) of the Hydrogen ion concentration (or, more accurately, Activity) expressed in molarity.…
