Why is pure water has pH 7 at room temperature?NO RUBBISH ANSWERS!!

Answered by admin @ 02/08/2021

Answer:

Explanation:

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).
