In the process of distillation, during condesation the temperature of water decreases Hence absorption of CO2 takes place and some H2CO3 is formed. This is an acid (though very weakly) so water turns acidic. Double distillation enhance this so theoritical pH is 7.0 but practically less than 7.0 (6.2 to 6.8)

∙ 11y agoFreshly distilled water WOULD INITIALLY have a pH of 7.0, but as soon as it is exposed to the air, which has CO2 in it, it begins to combine with the CO2 present in the atmosphere and after time, produces a mildly form of acid, carbonic acid. My daughter did a science fair project on why distilled water should NOT be used as a a control (ie, pH of 7.0) for exactly this reason.

∙ 10y agoBecause water absorb carbon dioxide from the atmosphere.
It's not ... unless its not pure.

∙ 11y agopH of distilled water is pH7. Adding acid will make the pH drop <7. Adding base will make the pH rise >7

Why is distilled water a base?
Distilled water is not a base.
Is baking soda mixed with distilled water a acid base or neutral?
Solution of baking soda is basic.
How is water a buffer?
Theoretically any system in which both the acid/base and its conjugate are present can be used as a buffer. Since pure water has hydroxyl and hydronium ions present at 10-7 M it can be technically called a buffering system. However, since the concentrations are so small and water offers practically no buffering capacity and in a common sense water is not used as a buffer for any reactions, only as a solvent.
What is formed when an acid and a base is mixed?
when an acid and a base combine, salt and water are formed. This process of reaction of an acid and base is called neutralisation.
Why is water always the product of neutralization?
acid + base → salt + water a salt and water are formed from the reaction between an acid and a base
Is distilled water an acid or a base?
its neutral.
Is distilled water base neutral acid?
Neutral.
Is distilled water a acid or base or neutral?
neutral
Is distilled water buffered?
No, distilled water is not a buffer. A buffer is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid.
Is distilled water acid or base or neutral?
Distilled water is neutral in nature. It is neither acidic nor basic and has a pH of 7.
Is a car battery a acid or base?
Wet cell, containing a mixture of sulphuric acid and distilled water.
Is a car battery a acid or a base?
Wet cell, containing a mixture of sulphuric acid and distilled water.
Why is distilled water a base?
Distilled water is not a base.
Is a battery a acid or a base?
A battery contains a mixture of around 35% Sulfuric acid and 65% Distilled Water.
Is baking soda mixed with distilled water a acid base or neutral?
Solution of baking soda is basic.
Is distilled water classified as a base?
Distilled water is neutral
Is liquid in car battery a base?
The liquid is electrolyte which is a 35% mix of sulfuric acid and 65% distilled water.
