It is measured on a scale from 0 to 14, on which 7 means the substance is neutral. pH values below 7 indicate that the substance is acidic and pH values above 7 indicate that it is basic or alkaline. Pure water has a pH of 7 which means that it is neutral. WebJan 30, 2024 · pH and pOH. Because the constant of water, K w is \(1.0 \times 10^{-14}\) (at 25° C), the \(pK_w\) is 14, the constant of water determines the range of the pH scale. To understand what the pK w is, it is important to understand first what the "p" means in pOH and pH. The addition of the "p" reflects the negative of the logarithm, \(-\log\). Therefore, … gpx touchscreen frozen
