Discussion Overview

The discussion revolves around a homework problem involving the reaction between copper sulfate (CuSO4) and iron (Fe) powder. Participants are trying to determine the minimum volume of Cu2+ solution needed to completely react with a specified mass of iron, while also considering whether to base the calculation on the formation of Fe2+ or Fe3+ ions.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant asks whether the calculation should be based on the reaction producing Fe2+ or Fe3+ ions.
  • Another participant suggests that the molar concentration of copper sulfate is necessary to calculate the moles involved in the reaction.
  • A subsequent post clarifies that the concentration of the CuSO4 solution is 1.0M.
  • A later reply encourages the original poster to show their approach to the problem, indicating that the solution may be straightforward but expressing confusion about where they are getting lost.

Areas of Agreement / Disagreement

Participants have not reached a consensus on whether to base the calculation on Fe2+ or Fe3+, and the discussion remains unresolved regarding the approach to the problem.

Contextual Notes

There is a lack of clarity on how to convert the mass or moles of Cu2+ into volume, and the implications of choosing between the two reaction equations are not fully explored.

Homework Statement


we are mixing CuSo4 (Cu2+) with an iron (Fe) powder and we are trying to determine whether Fe2+ forms or Fe3+
now the question is :
suppose that 1.0 g of iron is used in the experiment. what is the minimum volume of Cu2+ solution that must be added in order to completely react the iron? should this calculation be based on the reaction of Fe2+ or Fe3+ with Cu2+?

Homework Equations


Fe(s) + Cu2+(aq) ---> Fe2+(aq) + Cu(s)
2Fe(s) + 3Cu2+ ---> 2Fe3+(aq) + 3Cu(s)

The Attempt at a Solution


are we supposed to determine which equation uses the least Fe? and if so how are we supposed to change that mass or moles of Cu2+(aq) into volume?
id really appreciate some help :)
 
Physics news on Phys.org
You need molar concentration of copper sulfate to calculate moles.
 
oops sorry to include that its a 1.0M solution cuso4
 
Show how you are approaching the question, it is relatively easy and I have no idea where and why do you get lost.
