Why is pure water has pH 7 at room temperature |
|
Answer» 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).Please mark as brainliest |
