Describes a solution with a pH lower than the pH of distilled water?
A solution with a pH lower than that of distilled water would be acidic. This could be achieved by adding an acid such as hydrochloric acid or sulfuric acid to water. Acidic solutions have a pH below 7, with the lower the pH, the more acidic the solution will be.
Why is it necessary to rid distilled water of CO2?
Removing CO2 from distilled water is important because it can react with water to form carbonic acid, which can alter the pH of the water. This can affect experiments or applications that require water with a specific pH level. Additionally, removing CO2 helps prevent unwanted reactions in sensitive systems or equipment.
What happens when you mix equal parts nitric acid and distilled water?
When you mix equal parts nitric acid and distilled water, the solution will become diluted nitric acid. This mixture will have a lower concentration of nitric acid than the initial pure nitric acid solution. It is important to note that mixing acids with water should be done carefully to prevent splashing and to ensure proper dilution.
Why is salicylic acid more acidic than acetylsalicylic acid?
Salicylic acid dissociates in water to form a carboxylic acid group, making it more acidic compared to acetylsalicylic acid which has an ester group that is less acidic. The presence of the -OH group in salicylic acid contributes to its higher acidity compared to the -OR group in acetylsalicylic acid.
Can you Give me name of two pollutants found in air which make rain-water more acidic?
Two pollutants found in air that can make rain water more acidic are sulfur dioxide and nitrogen oxides. These pollutants can react with water in the atmosphere to form sulfuric acid and nitric acid, which then fall to the ground in the form of acid rain.

When CO2 is bubbled through distilled water at 25C why would the pH of the solution be reduced?
When CO2 is bubbled through distilled water at 25°C, it forms carbonic acid (H2CO3) by reacting with water (H2O). This lowers the pH of the solution because carbonic acid is a weak acid that increases the concentration of H+ ions in the water, making it more acidic.

Removing CO2 from distilled water is important because it can react with water to form carbonic acid, which can alter the pH of the water. This can affect experiments or applications that require water with a specific pH level. Additionally, removing CO2 helps prevent unwanted reactions in sensitive systems or equipment.
Is the solution Distilled Water acidic alkaline or neutral?
Distilled water is theoretically neutralDistilled water is water that has many of its impurities removed through distillation.Distillation involves boiling the water and then condensing the steam into a clean container.Hypothetically, distilled water should always be at a neutral pH 7. Immediately upon being exposed to air, however, distilled water's pH decreases and becomes more acidic. Neutralizing distilled water is possible, but its neutral pH does not last.

This mixture will have a lower concentration of nitric acid than the initial pure nitric acid solution.

Write short note on Acid Rain?
Acid rain" is a popular term referring to the deposition of wet (rain, snow, sleet, fog and cloudwater, dew) and dry (acidifying particles and gases) acidic components. A more accurate term is "acid deposition". Distilled water, which contains no carbon dioxide, has a neutral pH of 7. Liquids with a pH less than 7 are acidic, and those with a pH greater than 7 are bases. "Clean" or unpolluted rain has a slightly acidic pH of about 5.2, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid (pH 5.6 in distilled water), but unpolluted rain also contains other chemicals.[1]
Why is salicylic acid more acidic than acetylsalicylic acid?
Salicylic acid dissociates in water to form a carboxylic acid group, making it more acidic compared to acetylsalicylic acid which has an ester group that is less acidic. The presence of the -OH group in salicylic acid contributes to its higher acidity compared to the -OR group in acetylsalicylic acid.
Why is the pH of the ocean more acidic at night?
because there are more Carbonic acid on the air at night (from the trees) and it is solved in water and make it acidic.
Can you Give me name of two pollutants found in air which make rain-water more acidic?
Two pollutants found in air that can make rain water more acidic are sulfur dioxide and nitrogen oxides. These pollutants can react with water in the atmosphere to form sulfuric acid and nitric acid, which then fall to the ground in the form of acid rain.
Is sio2 more acidic than so2?
When dissolving CO2 in water it forms a weak acid: H2CO3. SiO2 will not dissolve in water, so it is not acidic (nor base)
Is BaCO3 barium carbonate more soluble in an acidic solution or pure water?
Barium carbonate (BaCO3) is more soluble in acidic solutions than in pure water. In an acid solution, the carbonate ion (CO3^2-) can react with protons (H+) from the acid to form carbonic acid (H2CO3), which is more soluble and can dissociate into water and carbon dioxide. This reaction helps increase the solubility of barium carbonate in acidic conditions.
Is acid rain more gaseous radioactive or more acidic than normal rain?
Acid rain is made from chemicals in the air mixing with water in the air. This makes the rain more acidic then normal rain.
