Mention the main conclusions derived from the Fountain experiment with ammonia.

Explanation

**Step-by-Step Solution:**

1. **Understanding the Fountain Experiment**: The fountain experiment with ammonia involves a setup where ammonia gas is dissolved in water, demonstrating its properties.

2. **High Solubility of Ammonia**: The first main conclusion from the experiment is that ammonia has a high solubility in cold water. This means that a significant amount of ammonia can dissolve in water, which is a key characteristic of this compound.

3. **Alkaline Nature of Ammonia**: The second conclusion is related to the behavior of ammonia in water. When ammonia dissolves in water, it increases the pH of the solution, making it alkaline. This is evidenced by the color change of red litmus paper to blue when it comes into contact with the ammonia solution.
