CLASS 13: Molecules in Solution Solutions 1- Define the following terms: solution , solvent , solute . Why does a solution have to be homogeneous ? 2- How are vitamins classified in terms of their solubility properties? 1) solution – one substance mixes very well with another substance (solute + solvent); Solute – thing being dissolved; solvent – thing doing the dissolving molecules must be distributed evenly 2) water soluble (C, B2) and fat soluble (A, D) Aqueous Solutions 1- Using molecular properties, explain why hydrocarbons such as methane (CH

Unformatted text preview: 4 ) are not soluble in water. 2- When CH 4 is forced into liquid water under pressure, what type of structure is formed by the H 2 O molecules? 3- Draw a diagram to explain why methanol (CH 3 OH) dissolves readily in water. 1) Cant interact with H2O b/c it has no partial charges 2) Clathrate structure (cage) creates iceberg effect of less randomness (wrong direction of entropy) 3) The polar region (O-H) interacts w/H2O and makes molecule soluble...
