What is the purpose of the Alka-Seltzer tablets in a homemade lava lamp?

Which of the following is NOT a step in making a homemade lava lamp?

Which of the following statements accurately describes the relationship between density and solubility in a homemade lava lamp?

What happens to the blobs of colored wax in a homemade lava lamp when the Alka-Seltzer tablet is first added?

How does the solubility of the Alka-Seltzer tablet in water relate to the chemical reaction that occurs in a homemade lava lamp?

Common household materials needed include water, vegetable oil, food coloring, and Alka-Seltzer tablets.
Not required: items like sand or sugar.

They create carbon dioxide gas when dissolved in water, causing bubbles to rise and fall, simulating lava movement.
This reaction enhances the visual effect of the lava lamp.

The primary ingredients for a homemade lava lamp include water and vegetable oil, as they have differing densities.

Density affects how layers of liquid behave; the denser liquid (water) sits below the less dense liquid (oil).
Solubility plays a crucial role when the Alka-Seltzer dissolves, impacting how gases and liquids interact.

When Alka-Seltzer is added, blobs of colored wax or water are created, initially rising due to gas bubbles forming around them before sinking as the bubbles pop.

The solubility of Alka-Seltzer in water initiates a chemical reaction that produces carbon dioxide gas, essential for creating the lava lamp's "lava" effect.
The visible motion in the lamp is heavily influenced by how the gas bubbles interact with the liquid layers.
