Can the reaction FeCl2 plus Cu equals Fe plus CuCl2 occur?

Answer 1

No it cannot. While in theory it appears that Copper and Iron could just switch places, this can not actually take place. Iron has a higher 'reactivity' than Copper does, so in a sense; the Iron holds on too tight to the Chlorine ions for the Copper ions to switch and take its place.

Answer 2

This may be a trick question. In any case, the first answer provided by Kukupuku is incorrect. The chemical equation looks good; the problem is, however, that HCl does NOT react with copper metal (Cu). One can boil copper powder in concentrated HCl for a week and nothing will happen. The reason is that the hydrogen ion is not a sufficiently powerful oxidizing agent to remove electrons from copper. Had Kukupuku checked the Electrochemical Series - a list of reduction or oxidation "half reactions" ordered beginning with those either with the highest negative standard potential or by those with the greatest positive standard potential relative to the standard hydrogen electrode (SHE), the standard reduction potential of which is zero by definition - then he would have clearly seen that H+ is incapable of oxidizing copper.

Cu + 2HCl -------> CuCl2 + H2

gives Cupric Chloride and Hydrogen gas.

Answer 3

Fe(aq) + CuCl2(aq) à Cu(s) + FeCl2(aq)

im tryna get the ionic, but this is the overall

Answer 4

Fe reacts with CuSO4, and replaces the Cu. This a single displacement reaction.

Fe + CuSO4 ----> FeSO4 + Cu

Answer 5

CuCl2 + Fe = FeCl2 +Cu

Answer 6

SO4 + Fe ==> FeSO4

Answer 7

FeCl2(aq) + Cu(s)

Answer 8

simple displacement reaction

Answer 9

no reaction
