CHEM 1B Chapter 14: Chapter 14 Properties of Solutions
Document Summary
To prevent water in cells from freezing & expanding, wood frog secrets glucose into its bloodstream lower freezing point. Concentrated solutions have a lower freezing pt than pure liquid. Concentrated glucose + water = ex. of solution. Majority component typically solvent & minority = solute. In most solutions, particles of solute interact w/ particles of solvent through imf. Aqueous solutions - water is solvent & solid, liquid, or gas is solute. Solubility = amount of substance that"ll dissolve in given amount of solvent. Depends on both nature"s tendency toward mixing & types of imf. Formation of a solution doesn"t necessarily lower pe of its constituent particles. Ex: formation of solution of two ideal gases, ar & ne. We cannot think of the mixing of 2 gases as lowering their pe tendency to mix related to entropy. Entropy = measure of energy randomization or energy dispersal in a system.
