Definition of ph scale in biology
WebPH Scale (chemistry) 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 … WebAcidic substances have pH between 0 and 7, and basic substances have pH between 7 to 14. A pH of 7 means that the substance is neutral. pH is a measure of the concentration of H+ ions or OH− ions in a solution. If there is a high concentration of H+, it is acidic. If there is a high concentration of OH−, it is basic (also called alkaline).
