Why can the pH of freshly boiled deionized water slowly become more acidic when left exposed to the atmosphere?

Because the air contains CO2,which is dissolved in the water and produces carbonic acid. Same effect asacid rain.

Why is deionized water weakly acidic?
The ion-exchange resins that are used to remove certain ions from the water to make it deionized sometimes leave a higher concentration of protons in the water, which makes it slighty acidic.
What happen to a metal exposed to an acidic mixtures?
acidic mixture or metal
How does litmus paper react when exposed to vinegar?
Litmus is used to test materials for their acidity. Blue litmus paper turns red when exposed to acid, so it would turn red when exposed to vinegar, which is acidic.
What happens to an iron exposed to an acidic mixture?

Why rain water in industrial areas is acidic?
In industrial areas, acidic gases such as sulfur dioxide is emitted to the atmosphere. When it rains, the gaseous acids dissolve in the raindrops, and such rains are known as acid rains.

Suggest why normal rain water is slightly acidic?
Normal rainwater has a pH of 5.6 (slightly acidic). This is because it is exposed to the carbon dioxide in the atmosphere. The carbon dioxide gets dissolved in the rainwater and forms carbonic acid (H{-2}CO{-3}).
Where does lemon juice lie on the pH scale?
Lemonade has a pH of about 2 or 3. Acidic substances have pH's below 7 and while bases have pH's above 7. Pure water (deionized) has a pH of 7.0. (Tap water is generally slightly acidic with a pH of ~6.5).
What is the most popular planet in space?
Venus because of it's acidic atmosphere
How does litmus paper react when exposed to vinegar?
Litmus is used to test materials for their acidity. Blue litmus paper turns red when exposed to acid, so it would turn red when exposed to vinegar, which is acidic.

What do you use litmus paper for?
to tell if a solution is acidic or basic (paper changes color when exposed to solutions)
What color is blue litmus paper when exposed to an acid?
Blue litmus become red in acidic solutions.
Which planet has an acidic atmosphere?
the planet that has acidic rain is planet unknown lol if u have a ps3 and online add me BlazinEagles
How pH paper distinguishes acid and bases?
pH paper changes color after being exposed to an acidic or a basic solution (depending on the paper). For instance, blue litmus paper will turn red after being exposed to an acidic solution, while red litmus paper will turn blue after being exposed to a basic solution. The addition of an acidic or basic solution to litmus paper causes a chemical reaction which changes the light absorbing properties of litmus, thus altering its color.
Will pH fluctuate in water?
Yes, because water absorb from atmosphere gases wit acidic potential (CO2, NO2, SO2, etc.) and become more acidic.
