Electrolysis

Electrolysis is defined as the process of breaking down ionic compounds into their constituent elements by passing a direct electric current through the compound in a fluid state. The cathode reduces cations, while the anode oxidizes anions. An electrolyte, electrodes, and some form of external power source are the main components required for conducting electrolysis. A partition, such as an ion-exchange membrane or a salt bridge, may also be used, but this is optional. These are primarily used to prevent the products from diffusing near the opposing electrode.

Question

Pewer Source
The diagram above shows an electrolytic cell used to plate a nail with zinc. The
mass of zinc plated on the nail with 8.00 x 10° C of electrons is
g.

Copper shingles make an expensive but long lasting roof. Over time, the shingles
develop a distinctive green patina from the copper (II) compounds that form on
the surface of the shingles. These compounds shield the copper underneath from
further oxidation.
Copper shingles shouldn't be fastened with iron nails. Why is this?
Select one:
O The nails will oxidize causing the shingles to come loose.
O The copper will react with the iron, oxidizing both the nails and shingles.
O The combination of iron and copper is a strong reducing agent.
O The nails will cause the copper to oxidize more quickly.

A chemistry student must write down in her lab notebook the concentration of a solution of potassium chloride. The concentration of a solution equals the mass of what's dissolved divided by the total volume of the solution. Here's how the student prepared the solution: • The label on the graduated cylinder says: empty weight: 1.55 g • She put some solid potassium chloride into the graduated cylinder and weighed it. With the potassium chloride added, the cylinder weighed 31.436 g. • She added water to the graduated cylinder and dissolved the potassium chloride completely. Then she read the total volume of the solution from the markings on the graduated cylinder. The total volume of the solution was 166.4 mL. What concentration should the student write down in her lab notebook? Be sure your answer has the correct number of significant digits. -1 g.mL x10 × Ś
