What is the pH scale and what does it measure? - BBC Bitesize

WebA pH (little p) of 7 only means neutral water at 25°C, but for other temperatures this means a pH above or below 7. This is due to the changing value of water's self-ionization constant, Kw, with temperature. At 25°C we know it to be 1.0 x 10^ (-14), but at something like 50°C it's about 5.5 x 10^ (-14). http://coolperiodictable.com/resources/acids-and-bases/pH-of-some-common-substances.php graduate school human resources https://primechaletsolutions.com
