Once upon a time, there was a young scientist named Lily. She was studying about solutions in her lab. One day, she was trying to understand the process of hydrolysis. She took a mixture of different ions and added water to it. To her surprise, the mixture underwent hydrolysis and the ions got separated one by one.

Lily wanted to measure the concentration of the ions in the solution, so she used a technique called molality. She found out that the ions were present in very low concentrations, but they still had a significant effect on the solution.

In the end, Lily learned that even a small change in the concentration of ions can lead to big differences in the properties of a solution. And that's why it's important to measure the concentration of ions in a solution using techniques like molality.

The end.

Reflections

1. What is hydrolysis?
2. What did Lily do in the lab to understand hydrolysis?
3. What technique did Lily use to measure the concentration of ions in the solution?
4. What did Lily learn about the effect of ions on a solution?
5. Can you think of any real-life examples where measuring ion concentration is important?
