Gallium is obtained by electrolysis of its chlorides. Write the anode and cathode electrode equations which occur if you were to electrolyze molten gallium chloride and give the overall balanced reaction.
At the anode you have Ga^3+ + 3e ==> Ga
At the cathode you have 2Cl^- ==> Cl2 + 2e
-------------------------------------------------------
overall: 2Ga^3+ + 6Cl^- ==> 2GaCl3
Note: GaCl3 actually occurs, like AlCl3, as the dimer; i.e., Ga2Cl6
Can't help on the other. Wouldn't anyway since that's answer mooching.

Can someone find the answers to Ecology Chemistry Unit Test
on pearson Please!? Please and thanks you soo much!!
Well, Mr./Ms. Inquirer, let's get electrified with gallium chloride electrolysis! Here are the juicy electrode equations you're craving:
At the anode (positive electrode):
2 Cl- (chloride ions) → Cl2 (gaseous chlorine) + 2e-
And at the cathode (negative electrode):
Ga3+ (gallium ions) + 3e- → Ga (molten gallium)
Now, let's put everything together and create a harmonious balanced reaction:
2GaCl3 (molten gallium chloride) → 2Ga (molten gallium) + 3Cl2 (gaseous chlorine)
Voila! You've got the overall balanced reaction. Time to give gallium chloride a shocking experience, don't you think?
To determine the anode and cathode electrode equations for the electrolysis of molten gallium chloride (GaCl2), we need to consider the half-reactions at each electrode.
Anode (Oxidation):
At the anode, oxidation occurs, resulting in the loss of electrons. Chloride ions (Cl-) are likely to be oxidized to chlorine gas (Cl2):
2 Cl- → Cl2 + 2 e-
Cathode (Reduction):
At the cathode, reduction occurs, resulting in the gain of electrons. Ga2+ ions are likely to be reduced to metallic gallium (Ga):
Ga2+ + 2 e- → Ga
Overall Balanced Reaction:
To obtain the overall balanced reaction, we combine the anode and cathode half-reactions and ensure that the number of electrons gained and lost are equal:
2 Cl- → Cl2 + 2 e- (Anode)
Ga2+ + 2 e- → Ga (Cathode)
By multiplying the anode half-reaction by 2 to balance the number of electrons lost and gained, we can combine the two half-reactions to obtain the overall balanced reaction:
2 Cl- + Ga2+ → Cl2 + Ga
Thus, the overall balanced reaction for the electrolysis of molten gallium chloride is:
2 Cl- + Ga2+ → Cl2 + Ga
