Ph

Numerically the ph is approximately equal to the negative logarithm of hydrogen ion concentration expressed in molarity. Ph 7 is neutral, above 7 is alkaline and below is acidic. p(otential of) H(ydrogen); 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 acidic and less than 7 is basic).The measure of the hydrogen ion concentration of a solution. The [[pH [[scales Indicates results from 1 to 14 where a ph below seven is acidic, 7 neutral and alkaline above 7. The higher the deviance from 7, the more acidic or alkaline the substance will be.
