Choose the balanced equation for the reaction. Au3+(aq) + Cu+(aq) → Au(s) + Cu2+(aq) Au(s) + Cu2+(aq) → Au3+(aq) + Cu+(aq) Au3+(
Rasek [7]

Answer:

Au3+(aq) + 3Cu+(aq) → Au(s) + 3Cu2+(aq)

1.35 V

Explanation:

Given that the reduction potential of

Cu^2+(aq) + e- -----> Cu^+(aq) is +0.15 V

While the reduction potential of

Au3+(aq) + 3 e- -----> Au(s) is + 1.50V

It is clear that the Cu^+(aq)/Cu^2+(aq) system is the anode while Au^3+(aq)/Au(s) system is the cathode based on the reduction potentials shown above. The number of electrons transferred (n) =3

E°cell = E°cathode - E°anode

E°cell= 1.50-0.15

E°cell= 1.35 V

One gram of Sn was electroplated from a SnCl, solution in 30 minutes. What was the current used?
Andrews [41]

Answer:

0.903 A

Explanation:

We have given mass of Sn = 1 gram

Time t=30 minutes=30×60=1800 sec

According to Faraday law m=zit

Where z is electron chemical equivalent

z is calculated by z=\frac{atomic\ mass}{nF} where n is number of element and F is Faraday constant

So z=\frac{atomic\ mass}{nF}=\frac{118.71}{2\times 96500}=0.000615

So 1=0.000615\times i\times 1800

i =0.903 A
