Answer: Cola is a substance with high acidity, so it is added sweetener. Explanation: Cola is a common substance in soft drinks. It is an acidulant substance, as it is composed of phosphoric acid and carbonic acid, creating a highly acidic environment in the drink, mainly due to the phosphoric acid account.

14.2: Acids- Properties and Examples - Chemistry LibreTexts

Nitric acid reacts with most metals, but the details depend on the concentration of the acid and the nature of the metal. Dilute nitric acid behaves as a typical acid in its reaction with most metals (e.g., nitric acid with magnesium, manganese or zinc will liberate \(\ce{H2}\) gas):

Calcium carbonate | CaCO3 - PubChem

Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for preventing and treating osteoporosis.

5 Chemical Weathering Examples and How They Occur

Carbonic acid is the culprit when it comes to the carbonation type of chemical weathering. As rain goes through the air and into the ground, it grabs carbon dioxide, creating carbonic acid. This weak acid reacts with the calcium carbonate in stones when it seeps into the cracks.
