Experiment # 4
Homes of Fumes
The objective of this test was to look into and recognize the chemical substance properties with the gases analyzed.
Gas| FLAME REACTION| GLOWING SPLINT| LIMEWATER REACTION| BROMOTHYMOL GREEN REACTION| Hydrogen| NO REACTION| В | В | В
Oxygen| В | BURNT BRIGHTER| В | В
Hydrogen & Oxygen| QUICK FIRE BURST| В | В | В
Carbon Dioxide| В | PUT THE FIRE OUT| NO REACTION| TURNED YELLOW| Alka Seltzer| В | В | BUBBLED| В
Breath| В | В | ENORMOUS BUBBLES| В
Structured off this experiment that made me realize that the reactions are much more different when you compare an acid or basic solution. Getting into these trials at home likewise proves a point in that understanding what type of reaction to expect is essential.
A. Provide two main reasons why we complete the gas generator check tubes almost to the add chemicals.
2. To receive as much gas as possible without any air
2. Some of the chemical substances could respond with the oxygen that is filling up the rest of the check tube
W. What happens to the zinc inside the hydrogen generation experiment?
2. It dissolves
C. How it changes the manganese in the air generation experiment?
* The manganese acted as a catalyst
D. Set a balanced formula for the response between 02 and H2?
-H2 & H2 +02= 2H20
At the. What is the function/purpose from the bromothymol green in the C02 experiment?
-To show just how acidic solutions react totally different to what would be the norm basic solutions
E. Bromothymol blue is definitely blue inside the presence of basic solutions, and yellowish in the presence of acid solutions. Should your solution is a murky green, what might you believe about a answer?
-It is actually a mixture of acidic and fundamental solutions
