Now in hassle number two, reduction of copper takes place and this copper or aqueous copper becomes copper solid. Now, this electrode is also copper solid but our concentration in beaker one is 0.5 molar so this guy is more concentrated and this guy is more dilute. So let's see what the net rethink reaction for this electrochemical cell is. So we add the oxidation reaction and the reduction reaction up and we get our net reactor to be the following notice that this copper solid and this copper solid cancel because they appear on both sides of the equation. Also the electrons cancel because they appear on both sides of the equation. What we are left with is this guy and this guy.
