Question 1 Report
The diagram above is an illustration of an experimental setup to test the action of
yeast. What test would be used to confirm the nature of the gas given off at?
Answer Details
The test that would be used to confirm the nature of the gas given off in the experimental setup is to pass the gas through lime water. This is because lime water (Calcium hydroxide solution) reacts with carbon dioxide gas, which is one of the gases produced during yeast fermentation, to form a milky precipitate of calcium carbonate. If the gas given off by the yeast is carbon dioxide, then the lime water will turn milky when passed through it, confirming the nature of the gas.
