www.ccri.eduBasic solutions are also described in terms of pH. In water the following relation exists: [H+1] x [OH-1] = K w = 1.0 x 10-14 at 25 ºC (2) Since [H+1] equals [OH-1] in pure water, by Equation 2, [H+1] must be 1 x 10-7 M. Therefore, the pH of distilled water is 7.

cpb-us-e1.wpmucdn.comability. Don’t confuse alkalinity with pH. pH measures the strength of an acid or base; alkalinity indicates a solution’s power to react with acid and "buffer" its pH — that is, the power to keep its pH from changing. To illustrate, we will compare two samples of pure water and buffered water. Absolutely pure water has a pH of exactly 7.0.
