1. Explain how you determined the polarity of all your compounds by first predicting the polarity of water, and then mixing different solutes and solvents to find the polarities of the other substances.
2. Which of your polarity and solubility predictions were correct?
3. Create three additional combinations of compounds from the materials in your experiment. Without preforming tests, determine if your chosen solutes and solvents would be soluble or insoluble. Explain how you can predict solubility without testing.
4. Were any of your substances difficult to identify as polar, nonpolar, or ionic?
5. Predict the polarity and molecular structure of formaldehyde, a compound used to preserve animal specimens, and ammonia, a compound used in many household cleaning products. Explain.
6. Based on their polarity, which compounds from your experiment could mix with formaldehyde and ammonia?
