Electroplating Zinc onto Copper: Calculating Time Needed

In summary, the conversation is about a science experiment that requires electroplating zinc onto a thin copper sheet. The desired zinc thickness is 140 and the charge carriers are divalent zinc ions. The density of zinc is 7140 and the electroplating apparatus operates at 1.40. The question is how long it will take for the zinc to reach the desired thickness. The person asking for help is having trouble understanding the problem and does not know which formula to use.

Wow. Can anyone please tell me how to approach this problem?

For a science experiment you need to electroplate zinc onto both sides of a very thin, 1.00 1.00 copper sheet. You want the zinc thickness to be 140 , and you know that the charge carriers in the ionic solution are divalent (charge ) zinc ions. The density of zinc is 7140 .

If the electroplating apparatus operates at 1.40 , how long will it take the zinc to reach the desired thickness?

Why don't you show us how far you got? You know, that thing in the template which somehow is missing from your message.

that's the thing. Mastering Physics homework assignments give problems that are not covered in lecture or in the book. That is why I don't even know how to approach this problem, or what formula to use :T
 

1. What is electroplating and why is it used?

Electroplating is a process in which a thin layer of one metal is deposited onto the surface of another metal. It is commonly used to improve the appearance or properties of a metal, such as making it more resistant to corrosion.

2. Why is zinc commonly used for electroplating onto copper?

Zinc is commonly used for electroplating onto copper because it is a relatively inexpensive metal that provides good corrosion resistance. Additionally, zinc has a lower melting point than copper, making it easier to deposit onto the copper surface.

3. How is the time needed for electroplating zinc onto copper calculated?

The time needed for electroplating zinc onto copper is calculated using Faraday's law, which states that the amount of metal deposited on a surface is directly proportional to the amount of electricity passed through the plating solution. This calculation takes into account factors such as the current, plating efficiency, and surface area of the copper.

4. What factors can affect the time needed for electroplating zinc onto copper?

The time needed for electroplating zinc onto copper can be affected by various factors such as the size and shape of the copper object, the concentration and temperature of the plating solution, and the type of zinc plating process being used. Other factors, such as the cleanliness of the copper surface and the quality of the electrical connection, can also impact the plating time.

5. How can the time needed for electroplating zinc onto copper be shortened?

The time needed for electroplating zinc onto copper can be shortened by increasing the current or conductivity of the plating solution, increasing the surface area of the copper object, or using a more efficient plating process. Additionally, ensuring that the copper surface is clean and the electrical connection is of high quality can also help to reduce plating time.
