Question

Ph value of distilled water

Answer 1

$<b ><font color ="purple" >$

The pH of a solution is a measure of the concentration of hydrogen ions. The term itself stands loosely for the "power of hydrogen," and it's the negative logarithm of the actual hydrogen ion concentration. This means that hydrogen ion concentration decreases with increasing pH and that a difference of one pH unit signifies a tenfold variation in hydrogen ion concentration. The pH value can vary from 0 to 14. Solutions with a pH between 0 and 7 are acidic, while those with a pH between 7 and 14 are basic. Pure distilled water should be neutral with a pH of 7, but because it absorbs carbon dioxide from the atmosphere, it's actually slightly acidic with a pH of 5.8.

TL;DR (Too Long; Didn't Read)

The pH of distilled water immediately after distillation is 7, but within hours after distillation, it has absorbed carbon dioxide from the atmosphere and become acidic with a pH of 5.8.

Hope you got it...
