Sea water ph scale
Webfluoride are in insignificant concentration in sea water (more than 400 times less concentrated than the sulphate ions); so, the difference between the pH T scale and the pH SWS scale is very small. That is why scientists are more focussed on pH T measurements. One of the methods for measuring the pH T of sea water is the use of m-cresol purple ... WebSince the beginning of the Industrial Revolution, the pH of surface ocean waters has fallen by 0.1 pH units. Since the pH scale, like the Richter scale, is logarithmic, this change …
