WebOct 22, 2024 · Pure water has a neutral pH of 7, which is neither acidic (less than 7) nor basic (greater than 7). The water molecule is highly cohesive — it is very sticky, meaning water molecules stick to each other. WebFor those who want a more complicated answer, pH is defined: pH = -log 10 [H+], where [H+] is the concentration of H+ , expressed in moles/liter. In pure water near room temperature, the concentration of H+ is about 10-7 moles/liter, which gives a pH of 7.
