Question

Read the text.
You have probably heard of the pH scale, which measures how acidic or basic different solutions are. A solution's acidity or basicity is related to its concentrations of hydronium ions and hydroxide ions. When a strong acid is added to a solution, atoms in the solution break apart to form hydronium ions. This leads to a more acidic solution. When a strong base is added to a solution, atoms in the solution break apart to form hydroxide ions. This results in a more basic solution.
Match causes with their effects.

Answer 1

To match causes with their effects from the provided text, we can summarize them as follows:

1. **Cause: Adding a strong acid to a solution**
- **Effect: Formation of hydronium ions, resulting in a more acidic solution.**

2. **Cause: Adding a strong base to a solution**
- **Effect: Formation of hydroxide ions, resulting in a more basic solution.**

If you have specific options to match from a list, please provide them, and I can help you further!
