How To Grow Copper Crystals with Electricity

The video tutorial demonstrates how to grow copper crystals at home using the electrowinning process. It explains the setup, including materials like a glass container, copper wire, and copper sulfate solution. The tutorial covers the role of the power supply and current in crystal growth, emphasizing experimentation to achieve desired results. The process involves reversing the cell setup to observe different growth patterns, resulting in a large, pure copper crystal.

What is the primary purpose of the electrowinning process in growing copper crystals?

• To deposit pure metal onto an impure surface

• To create a chemical reaction with copper sulfate

• To dissolve copper into the solution

• To insulate the copper wire

In the electrowinning setup, what is the role of the anode?

• To conduct electricity

• To receive copper

• To deposit copper

• To insulate the wire

How does the concentration of copper sulfate solution affect the crystal growth?

• It decreases the speed of growth and makes it irregular

• It increases the speed of growth but makes it more irregular

• It has no effect on the crystal growth

• It makes the crystal grow slower but more regular

What should be done immediately after removing the crystal from the solution?

• Place it in a copper sulfate solution

• Put it in water to remove excess solution

• Expose it to air for drying

• Dry it with a cloth

What was observed when the cell setup was reversed during the experiment?

• The crystal dissolved completely

• The crystal stopped growing

• The copper dendrites grew downwards

• The copper dendrites grew up the side of the container
