WebOct 19, 2024 · pH is the indicator for acidity and alkalinity. If the pH scale ranges from 1 to 14, anything below 7 is acidic and above 7 is basic. Besides basic or acidic water, pure water has a neutral pH level of 7. Additionally, pH is a good indicator of soft or hard water. 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).
