The purpose of this experiment is to discover the physical and chemical properties of the studied gases. In discovering these properties it allows the student or observer the ability to identify these gases when they come into contact with them.
Before I began the procedure I gathered all my supplies from the given list in the manual. From there I began the actual experiment and diluted the HCL placed in a test tube and then placed the ZN in the tube as well. I placed the stopper and gas delivery plastic system on the test tube and arranged the tube in the well plate. I then took the test tube filled with water inverted it and placed on top of the gas delivery system, I had the well plate in a large bowl in case of flow over. I then removed and placed my thumb over the opening so gas wouldn’t escape I lit a match and held it approx 1 cm away and allowed a small drop from the pipet onto the flame to observe the reaction. From here I took my pipet bulb and marked it in 3 equal parts with a marker. I filled the pipet with water and set it into the gas generation tube. When it was about 2/3 full of gas I removed it and set it facing down into the well holder as per the directions. I then cleaned up the other test tube disposed of the acid and washed the test tube and rubber stopper with water thoroughly. I then began the oxygen portion of the experiment where I placed some Mn into a test tube. I added some hydrogen peroxide and filled to nearly the top. I placed the rubber stopper with gas delivery system and put into the well plate in a straight postion. I filled the pipet with water and once again inverted it and placed in on top of the gas delivery system. I then watched as it became displaced with oxygen and removed it placed my thumb over it so it wouldn’t escape. I took a wooden toothpick and lit it then blew it out quickly while it was still hot and had a red glow to the stick I inserted the toothpick into the pipet filled with...
