I would love some input on a few problems, listed below. My answers follow the questions
1. Would it be feasable to store a solution of lead nitrate in a container of metallic zinc? Why or why not?
No, it would not. A chemical reaction takes place, as the lead oxidizes the zinc.
2. Would it be feasable to store a solution of lead sulfate in a container of metallic silver? Why or why not?
no idea.
3. Would you expect jewelry made of an alloy of silver or copper to tarnish (react) in an environment where chlorine fumes were present?
Yes, because it is a strong oxidizing agent.
You apparently read the two reponses (mine and the one from GK) so why are you posting it again? By the way, I agree with GK that it depends somewhat upon the alloy and I also agree that most tarnishes we think of is with the sulfide; however, I still think a copper alloy or a silver alloy will react with Cl2 fumes, especially so in humid environments.
I am so sorry for the double post, it was completely accidental. You and GK had very good answers, and I really appreciate the depth and speediness of your response!
1. To determine if it is feasible to store a solution of lead nitrate in a container of metallic zinc, we need to consider the reactivity between the two substances.
To find the answer, we can look up the reactivity series of metals. The reactivity series tells us the order in which metals react with other substances.
Zinc is less reactive than lead. Lead nitrate, on the other hand, contains lead, which is more reactive than zinc. Generally, when a more reactive metal is placed in contact with a less reactive metal in a solution, a redox reaction occurs, where the more reactive metal will oxidize the less reactive metal.
So in this case, we would expect the lead in the lead nitrate to react with the zinc in the container, leading to the formation of a new compound and the release of zinc ions into the solution. Therefore, it is not feasible to store a solution of lead nitrate in a container of metallic zinc.
2. Unfortunately, without further information, it's difficult to determine if it is feasible to store a solution of lead sulfate in a container of metallic silver. We would need to know the reactivity of silver with lead sulfate.
Alternatively, we could directly look up information about the reactivity of silver with lead sulfate in a reliable source such as a chemistry reference book or a scientific database. This information would provide a more conclusive answer and explain the reasons behind it.
3. To determine if jewelry made of an alloy of silver or copper would tarnish in an environment with chlorine fumes present, we need to consider the reactivity of these metals with chlorine.
Chlorine is a strong oxidizing agent, meaning it readily accepts electrons from other substances. Both silver and copper have a lower reactivity compared to chlorine. When exposed to chlorine fumes, these metals can undergo oxidation reactions.
As a result, the silver or copper in the jewelry can react with chlorine, forming metal chloride compounds. These compounds are often discolored and are responsible for the tarnishing of the jewelry.
In conclusion, in an environment with chlorine fumes present, jewelry made of an alloy of silver or copper would be expected to tarnish due to the reaction between the metal and the chlorine.
