Suppose you test a sample of a carbonated beverage with concentrated nitric acid and 2.5% ammonium molybdate, and a precipitate forms. What would this tell you about your carbonated beverage? a. This will tell you that the test solution turned into a solid. Carbonation refers to carbon dioxide dissolved in a liquid, and the rate at which carbon dioxide dissolves or is soluble depends on temperature. b. Testing a sample of a carbonated beverage would prove to be carbonated. c. A precipitate forming would show the beverage contains calcium ions. d. The carbonated beverage would test positive for ammonium ions. e. The carbonated beverage may have similar contents to the milk. f. The test would tell you that the carbonated beverage contains phosphate.
