Document Summary

Che2a - lecture - ch 4 solutions, concentration, molarity, stoichiometry of solutions, types of reactions. Post-lab due date extended due to technical. Dr. enderle"s practice exam on class website. Ch 4 redox reactions not on exam. Solvent - medium that the solute is dissolved in. Put table sugar in water (polar compound) Hydrogen from water molecule bonds to oxygen in table sugar. Oxygen from water molecule bonds to hydrogen in table sugar. Surrounding the particles of solute by molecules by molecules of solvent. If the solvent is h2o, the solvation is called hydration. Solvation doesn"t always mean water, need to specify (ie: hydration) When ionic compounds dissolve, they are all over and spread out throughout water (solvent) Oxygen molecule in water is negative, so sodium ion is surrounded by oxygen molecules from the water molecule. Chloride molecule is surrounded by hydrogen molecule from the water molecule. Molarity - moles of solute/ liter of solution.
