WebpH är ett logaritmiskt mått på surhet, det vill säga på aktiviteten av vätejoner (H +) i en lösning (egentligen oxoniumjoner, H 3 O +, en vattenmolekyl med en extra proton, det vill säga en extra H + ). Lösningar med låga p H-värden kallas sura och de med höga kallas basiska. Lösningar som har p H 7 (vid 25 °C) kallas neutrala. The pH scale ranges from 0 to 14, with a pH of 7 indicating neutrality, values less than 7 indicating acidity, and values greater than 7 indicating basicity. The pH scale is based on the hydrogen ion concentration, with each pH value representing a tenfold difference in hydrogen ion concentration.
