To the copper half-reaction, we add two electrons: Cu ---> Cu 2+ + 2e¯ One point of concern: notice that each half-reaction wound up with a total charge of zero on each side. This is not always the case. You need to strive to get the total charge on each side EQUAL, not zero.

WebComplete reaction of the provided chlorine would produce mol HCl produced = 2 mol Cl 2 × 2 mol HCl 1 mol Cl 2 = 4 mol HCl The chlorine will be completely consumed once 4 moles of HCl have been produced. Since enough hydrogen was provided to yield 6 moles of HCl, there will be unreacted hydrogen remaining once this reaction is complete. WebOxidation refers to the loss of electrons, while reduction refers to the gain of electrons. Each reaction by itself is called a "half-reaction", simply because we need two (2) half-reactions to form a whole reaction.
