WebbAutoionization of water. Since acids and bases react with each other, this implies that water can react with itself! While that might sound strange, it does happen - − water molecules exchange protons with one another to a very small extent. We call this process the autoionization, or self-ionization, of water. WebbA pH range between 1 and 7 is considered an acidic level, and from 7 to 14 is considered the alkaline level of water. I found in my research that drinking water that has a neutral pH (i.e., between 6.5-8.5) is best suited for consumption. Water with an acidic pH, i.e., below 6.5, can be harmful. open hp printer assistant software 8630WebbIf pK= 13.36 at 50°C, the pH of pure water at the same temperature is (a) 7.
