Questions & Answers

Q: What caused the failed growth of lead crystals on a larger scale?

The low concentration of lead acetate in the solution may have contributed to the inability of the lead to grow downwards.

Q: What is lead sponge and how is it formed?

Lead sponge is a combination of lead and zinc with a weak, pseudo solid structure held together by friction. It forms when zinc reacts with lead acetate.

Q: What are the potential uses of lead sponge?

Lead sponge is commonly used as the negative electrode in lead-acid car batteries due to its high surface area. It has potential for other applications as well.

Q: How did the different experiments with lead and zinc granules yield varied results?

The concentration of lead acetate, the addition of powdered lead and zinc, and the use of different techniques influenced the formation of lead sponge and crystals.

Summary & Key Takeaways

  • The creator attempted to grow lead crystals on a larger scale, but due to insufficient lead acetate, the process failed.

  • They added powdered zinc to the lead solution, resulting in the formation of lead sponge, a weak network of lead and zinc.

  • Further experiments with different techniques and additions of zinc granules were conducted, leading to varied results and observations.
