Ultimately, each handful, cup, or scoop removed from one of these mixtures will have a different distribution of ingredients. Solubility of one fluid (liquid or gas) in another may be complete (totally miscible; e.g., methanol and water) or partial (oil and water dissolve only slightly). The solubility of ___________ decreases as temperature increases. In the Homemade Slushies activity, students make slushies and explore the science behind how using a salt-water solution helps the slushy mixture form ice crystals. These compounds are consumed by humans: caffeine, acetaminophen, and vitamin D. Identify each as primarily hydrophilic (water soluble) or hydrophobic (fat soluble), and predict whether each is likely to be excreted from the body rapidly or slowly. For example, glucose with its five OH groups is hydrophilic. The resulting lemonade is a homogeneous solution because, once stirred in, the substances are uniformly combined and should not separate when the lemonade is left standing. 2 Table sugar C12H22O11 45 He then puts 50 grams of salt in 100 grams of water. C. Heat up the water first because it increases solubility of the powdered mix.
