Ph of seven
WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic.

Well, neither NaX + nor ClX − will react with water in any protolysis reaction. [We do not consider any ionic strength effects on the pH in this reasoning.] Suppose you titrate a weak base with a strong acid: NHX3 + HCl = NHX4X + + …
http://chemistry.elmhurst.edu/vchembook/184ph.html WebThe 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.
WebMar 26, 2016 · The pH scale goes from 1—14. A pH of 7 is neutral, meaning that the amount of hydrogen ions and hydroxide ions in a solution are equal. For example, water has a pH of 7 because when water breaks up, the split is equitable into one …
