pH вредност

pH вредност

Degree of acidity or alkalinity measured on a scale from 0 to 14 with 7 the neutral point. Measurement of pH is important to quality control in making paper and pigments and in the preparation of platemaking chemicals. PH control of press fountain solutions is also essential to assure maximum plate-life and uniform ink drying. From 0 to 7 is acid; from 7 to 14 is alkaline.
