Test to detect H 2 gas: When burning matchstick is kept on the mouth of this test tube, pop sound is heard which confirms the presence of H 2 gas. The evolution of gas is confirmed by the bubble formation in soap solution. to liberate hydrogen gas and corresponding salt. It is observed that active metals like zinc react with strong bases like NaOH, KOH etc. Name the gas which will be evolved when the same metal reacts with dilute solution of a strong acid. Write the equation of the chemical reaction involved and the test to detect the gas. When the content are warmed, a gas evolves which is bubbled through a soap solution before testing. (ii) If CO 2 is passed for long duration through lime water, the white precipitate formed dissolves due to the formation of soluble calcium hydrogen carbonate and the solution becomes clear.ΔΆ mL of sodium hydroxide solution is added to a few pieces of granulated zinc metal taken in a test tube. (i) When CO 2 is passed through lime water for short interval of time, it turns milky due to the formation of insoluble calcium carbonate. (ii) for a long duration? Also write the chemical equations for the reactions involved. What is observed when carbon dioxide gas is passed through lime water Hence, oxides of non-metals are acidic in nature. Calcium hydroxide, which is a base, reacts with carbon dioxide to produce salt and water. For example, the reaction between carbon dioxide and calcium hydroxide. Oxides of non-metals react with bases to form salt and water.
