part a observe the substances in the test tubes for 15 minutes. in the table, describe whats happening in each test tube, including any evidence of a chemical reaction. remember that evidence of chemical reactions can include change in color, change in smell, change in temperature, formation of a solid, or formation of bubbles. if theres no observable change in a test tube, write “no reaction.” test tube chemicals description of the reaction 1 iron and copper(ii) sulfate 2 copper and hydrochloric acid 3 zinc and iron(iii) nitrate 4 zinc and magnesium sulfate 5 zinc and hydrochloric acid 6 iron and hydrochloric acid
Answer
Explanation:
Step1: Analyze test - tube 1
Iron is more reactive than copper. Iron will displace copper from copper(II) sulfate solution. The blue - colored copper(II) sulfate solution will turn pale green (due to the formation of iron(II) sulfate), and a reddish - brown solid (copper) will deposit.
Step2: Analyze test - tube 2
Copper is less reactive than hydrogen in the reactivity series. So, copper does not react with hydrochloric acid. There will be no reaction.
Step3: Analyze test - tube 3
Zinc is more reactive than iron. Zinc will displace iron from iron(III) nitrate solution. The solution color may change, and a solid (iron) may be deposited.
Step4: Analyze test - tube 4
Zinc is less reactive than magnesium. So, zinc does not react with magnesium sulfate solution. There will be no reaction.
Step5: Analyze test - tube 5
Zinc is more reactive than hydrogen. Zinc reacts with hydrochloric acid to produce hydrogen gas (bubbles will be formed) and zinc chloride.
Step6: Analyze test - tube 6
Iron is more reactive than hydrogen. Iron reacts with hydrochloric acid to produce hydrogen gas (bubbles will be formed) and iron(II) chloride.
Answer:
| Test Tube | Chemicals | Description of the Reaction |
|---|---|---|
| 1 | iron and copper(II) sulfate | Solution turns pale green, reddish - brown solid deposits |
| 2 | copper and hydrochloric acid | No reaction |
| 3 | zinc and iron(III) nitrate | Solution color changes, solid deposits |
| 4 | zinc and magnesium sulfate | No reaction |
| 5 | zinc and hydrochloric acid | Bubbles are formed |
| 6 | iron and hydrochloric acid | Bubbles are formed |
