1.	Two set ups as given below were arranged to identify the gas evolved when dilute hcl was added to zn granules. which one is the most appropriate and why?
Answer» The most appropriate SETUP for the detection of gas would be Step 2.Explanation:Zinc is a metal, so when it reacts with an acid, it produces a salt and releases HYDROGEN gas.The released hydrogen gas is detected by bringing a match STICK near the test tube. The hydrogen gas burns with a pop sound.The chemical equation for the reaction of zinc with hydrochloric acid follows:Gases rises up and is EASILY detected when the capillary is not in the solution.Hence, setup 2 is the most appropriate for the detection of hydrogen gas.
