Chapter 9 Introduction to Solutions and Aqueous Reaction Solutions 1 Solutions sol n a homogeneous mixture a ex salt water 2 Solute the component that is the minority of the solution a ex salt is the solute 3 Solvent the component that is the majority of the solution a ex water is the solvent 4 Aqueous solution a indicated with aq b means in water 5 Two solutions of the same mixture can differ by concentration a Concentration the amount of solute in a specific volume b Molarity moles of solute volume of solvent i VOLUME MUST BE IN LITERS ii molesL M molar c typically the solute is weighed molesmassmolar mass i typically the concentration is the target 1 ex 5M NaCl how many L gt moles gt mass d M ratio of moles molecules to a volume 6 2M NaCl vs 15M NaCl a Dilute solution small amount of solute compared to solvent 2M bc smallerM value b Concentrated solution large amount of solute compared to solvent 15M be larger M value 0 There s not a specific threshold in these situations one is just considered dilute and the other is considered more concentrated Dilution 1 Stock Solutions concentrated form of a solution a can be used to make dilute solutions by adding more solvent gt dilution b when you take an amount of volume from a container of a solution you know the number of moles you re taking just make sure the volume is in liters Solutions dissolve 1 solids are held together by solutesolute interaction 2 solutesolvent interaction must be stronger than solutesolute interactions for the solute to dissolve 3 NaCl in H20 a Na is and O is so they attract to each other 4 NaClaq means that it is in water a you re actually seeing under a microscope Naaq and Cl39aq ions separate the ionic compound has been dissociated and broken apart into ions b the Na and the Cl39 are what are physically in the solution i You should be able to balance the reaction NaClaq gt Naaq Cl39aq
