Title: Identifying pH Levels of Various Compounds

Task: Indicate whether each of the following compounds will give an acidic, basic, or neutral solution when dissolved in water.

- **Ammonium Perchlorate**  
- **Potassium Nitrite**  
- **Calcium Iodide**  
- **Potassium Cyanide**  

Options:  
1. The pH will be less than 7.
2. The pH will be approximately equal to 7.
3. The pH will be greater than 7.

Diagram Description:  
The diagram presents a matching exercise with four compounds to be matched with three possible pH outcomes. Arrows are used to indicate which pH level each compound corresponds to.

Instructions: Use references if necessary to determine the properties of each compound and match them to the appropriate pH category. Your score is based on correct matches; incorrect matches do not incur penalties.
