What Is the Meaning of a Ph Scale? Sciencing

WebTechnically, the pH scale measures the logarithmic concentration of hydrogen (H+) and hydroxide (OH-) ions, which make up water (H+ + OH- = H20). When both types of ions are in equal concentration, the pH is 7.0 or neutral. Below 7.0, the water is acidic (there are more hydrogen ions than hydroxide ions). WebFeb 27, 2024 · H + and OH – ion concentration are equal. i.e. [H +] = [OH –] = 1 x 10-7 mole dm-3; Thus concept of ionic products of water helps us in classifying aqueous solutions as acidic, basic and neutral. pH and pOH of a solution: pH of a solution: The negative logarithm to the base 10 of molar concentration of H + ions in a solution is called as pH ...
