How many hydrogen ions are in a ph of 7
WebIn many cases, we are concerned with whether the value of pH is above or below seven. This is because when water naturally decomposes into H+ and OH−, it produces 10−7 hydrogen ions. Plugging this in to our equation, pH=−log10[10−7] pH=7 And we arrive at our definitions of acids and bases. http://chemistry.elmhurst.edu/vchembook/184ph.html
