Question

hi guys how will you prove that the pH of neutral water is 7?​

Answer 1

Explanation:

1. Since at room temperature in pure water, that concentration is very close to 10-7M, so the pH is 7 . Moreover water has pH of 7 at temperature of 25 degree Celsius & it is "neutral" because the concentration of hydroxide ions (OH-) is also 7 (pOH=7)and thus balances out the concentration of hydrogen ions (pH=7).

Answer 2

water is both acid and a base
