What is the chemical reaction with copper?

Click For Summary

Discussion Overview

The discussion revolves around the chemical reaction involving copper, sodium chloride (NaCl), and water (H2O). Participants explore whether a reaction occurs under various conditions, including the presence or absence of air, and the effects of applying an electric potential.

Discussion Character

  • Exploratory
  • Debate/contested
  • Experimental/applied

Main Points Raised

  • One participant inquires about the chemical reaction that occurs when copper is combined with NaCl and water.
  • Some participants question the assumption that a reaction will occur, suggesting that under certain conditions, nothing will happen.
  • It is proposed that if the solution is not in contact with air, no reaction will take place, while contact with air may lead to different outcomes.
  • One participant shares an experimental observation where applying a 6V potential resulted in oxidation of copper and the production of an unidentified gas, speculating on the nature of the gas.
  • Another participant encourages further investigation into the gas produced and the potential discoloration of the copper.

Areas of Agreement / Disagreement

Participants express differing views on whether a reaction occurs, particularly in relation to the presence of air and the application of an electric potential. The discussion remains unresolved regarding the specifics of the chemical processes involved.

Contextual Notes

Participants have not reached consensus on the conditions under which a reaction may or may not occur, and there are uncertainties regarding the nature of the gas produced during the experimental setup.

Copper + NaCl + H20 = >> ?
Does anyone have any suggestions on what chemical reaction will occur in above example?
Thanks in advance for any suggestions

Why do you think there will be a reaction?

Please note: if it is a homework, you are breaking forum rules again.

This is not a homework, but I would like to know this chemical reaction, that is all.
Does anyone have any suggestions?
Thanks in advance for any suggestions
 
Nothing will happen.

I am not talking about what happen is within 5 seconds, what happen is on the next 3 months?
Does anyone have any suggestions?

If the solution is not in contact with air, nothing will happen. If the solution is in contact with air, it will be not a reaction between copper, water and sodium chloride.

So what happen if the solution is in contact with air?

I actually tried this today, except I also applied approximately a 6V potential to it. I got oxidation of the copper wire I was using and a gas. I am not sure what the gas was. At first I thought it was H2 gas from the water being electrolyzed (which I was trying to do), but there was not enough gas coming out of the positive end for that to be it I do not think. I checked the pH and insofar as litmus paper is accurate, it had remained a neutral solution.

It looks like you are beginning to answer questions yourself. How could you test for H2? What other possible gases could it be, if not H2? Did the copper discolor? Keep it up!
