Question

Predict the products that would be obtained at the anode and at the cathode in the following electrolyses: aqueous 1.0 M copper(II) chloride, using copper electrodes, aqueous 1.0 M iron(III) sulfate at graphite electrodes, and aqueous 1.0 M silver nitrate in 1.0 M HNO_3 at graphite electrodes. the reactions between zinc metal and aqueous copper(II) sulfate in the Daniel cell is exothermic. what would be the effect on the voltage of increasing the temperature? explain your answer using lechatelier's principle. construct a fully labeled concentration cell using Ag/Ag^+ half-cells. pick [Ag^+] values for each half-cell, and calculate the resulting voltage.

Explanation / Answer

1-

a- for 1 M copper chloride using copper electrode

anode-chlorine gas, cathode-copper metal deposits

b- anode- O2 gas, cathode-iron metal deposits

c- anode- O2 gas, cathode- Siler metal deposits
