Document Summary

Chapter 11: solutions and colloids: solute = the thing that is being dissolved. **note: b and c were ionic electrolytes: covalent electrolytes, some solutions prepared from covalent compounds are conductive because the solute molecules react chemically with the solvent to produce ions, hcl dissolved in water. As a pure gas, hcl has no ions, but when dissolved in water, it separates into h+ and cl-. Its molecules react with water because hcl is an acid: hcl is a strong acid strong electrolyte as well. Bad for health of things that live in water. Layers form when both are mixed": partially miscible - moderate mutual solubility. Usually form two layers when mixed: solutions of solids in liquids, general trend of increasing solubility with increasing temperature. But there will also be some solute molecules at the top, which decreases the surface area available for solvent molecules, and therefore reduces the vapor pressure for solvent.
