The pH scale is used to rank solutions in terms of how acidic or how basic they are. It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution. hna enterprises kurunegala

"Webb24 jan. 2016 · Here self ionization of water will also take place which will increase H + concentration and will reduce OH-concentration. Also [H +] from water will not be equal to 10-7 due to common ion effect. Net [H+]=10-pH. Also [H +] = [H 3 O +] because a single H + combines with a single water molecule to give H3O+ without involving OH-as you … " - H + ion concentration
