Exercise 2: Gas and Reactions
Data Table 2. Carbon Dioxide Reaction Observations. Please be local and detailed
Ca(OH)2 + CO2
Gas bubbles appeared closely presently. Disintegration became semisemiturbid white in falsification.
CO2 + BTB
Bubbles formed and disintegration changes falsification from cerulean to yellow/copper
CO2 + Flame
The glisten went out closely immediately.
Ca(OH)2 + Antacid/soak gas
Antacid/soak gas + Smoldering toothpick
Ca(OH)2 + Breath
Solution turns lightly semisemiturbid and chalky in appearance
A. Write a balanced chemical equation (delay phases) for the reaction of carbon dioxide and limesoak (Ca(OH)2). What are the visible descriptions of the products that are formed (i.e., what do they behold relish)?
B. When the bromothymol cerulean (BTB) was unguarded to the CO2 gas, what falsification was the disintegration? Did the falsification denote closeness of an sore or vile? Teach how you comprehend this.
C. Did the reaction among the antsore tablet and the tap soak yield hydrogen, oxygen, or carbon dioxide gas? Using your results from Exercise 1 and Exercise 2, teach how you came to gather the individuality of the gas that was formed. Be local.
D. Based on your contemplation of the reaction that occurred when limesoak was unguarded to your inspiration, what gas did you give-out? Using your contemplations from Data Table 2, teach how you came to gather the individuality of the gas. Be local.
E. What is another incomplex way to originate carbon dioxide gas?
F. Carbon dioxide is used in established types of vital-principle extinguishers. Based on what you literary in thi lab, what would happen if the extinguisher was populated delay oxygen gas? What encircling hydrogen gas?
