Acid rain is acidic and is caused by emissions of sulfur dioxide and nitrogen oxides that react with water vapor in the atmosphere to form sulfuric and nitric acids. It is not radioactive, but the acidity can cause harm to the environment and living organisms.
Nitric acid is more acidic than nitrous acid. This is because nitric acid has a lower pKa value (–1.3) compared to nitrous acid (3.3), indicating that nitric acid readily donates a proton in solution, making it a stronger acid.
Methanesulfonic acid is more acidic than propanoic acid. This is because the sulfonic acid group in methanesulfonic acid is a stronger acid group compared to the carboxylic acid group in propanoic acid.
Sulfuric acid is generally considered more acidic than nitric acid. This is due to sulfuric acid's ability to donate two protons in solution, making it a stronger acid. Nitric acid can only donate one proton.
3-methyl butanoic acid is more acidic than butanoic acid because the presence of the methyl group in 3-methyl butanoic acid increases the electron-withdrawing effect, making the molecule more acidic by stabilizing the conjugate base.
Formic acid is more acidic than benzoic acid. This is because formic acid has a simpler molecular structure with a hydrogen atom attached to a carboxyl group, making it easier to release the acidic hydrogen ion compared to benzoic acid, which has a more complex aromatic ring structure.
Acid rain is made from chemicals in the air mixing with water in the air. This makes the rain more acidic then normal rain.
Normal rain is slightly acidic, with a pH around 5.6 due to the natural presence of carbon dioxide in the atmosphere. Acid rain, on the other hand, has a lower pH (below 5.6), caused by pollutants such as sulfur dioxide and nitrogen oxides reacting with water in the atmosphere.
Nitric acid is more acidic than nitrous acid. This is because nitric acid has a lower pKa value (–1.3) compared to nitrous acid (3.3), indicating that nitric acid readily donates a proton in solution, making it a stronger 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.
Hydrochloric acid is more acidic than picric acid. Hydrochloric acid fully dissociates in solution to release hydrogen ions, resulting in a lower pH compared to picric acid, which is a weaker acid that does not fully dissociate in solution.
Not at all, but it depends on how dilute the sulphuric acid, but usually no.
Citric acid is more acidic than vinegar. The pH level of citric acid is around 2.2-3.5, while the pH level of vinegar is around 2.4-3.4. Therefore, citric acid has a slightly lower pH level, making it more acidic.
Acid rain is more acidic than lemon juice. Lemon juice has a pH of around 2, while acid rain typically has a pH in the range of 4.2 to 4.4 due to the presence of sulfuric and nitric acids.
