CHEM - Describing Tests for Gases
Chemistry, Chemical Tests, Gases- IBDP | DSE | GCE | IAL | AP Chemistry
There are a number of chemical tests to identify different gases such as hydrogen, oxygen and ammonia.🤔
Have a look at this example👀
Part I- Hydrogen
Test: Insert a burning splint into the test tube containing hydrogen.
The presence of H2 (g) results in a 'pop' sound
Part II- Oxygen
Test: Insert a glowing splint into the test tube containing oxygen.
The presence of O2(g) relights the glowing splint
Part III- Carbon Dioxide
Test: Bubble the gas through limewater.
The presence of CO2 turns the limewater milky
Part IV- Ammonia
Test 1: Insert a piece of moist red litmus paper into the gas.
The presence of NH3(g) turns moist red litmus paper blue
Test 2: Dip a glass rod in dilute hydrochloric acid and insert it into the gas.
The presence of NH3(g) results in the formation of dense white fumes
Part V- Chlorine
Test: Insert a piece of moist blue litmus paper into the gas.
The presence of Cl2(g) turns moist blue litmus paper red and then bleaches it
