In the previous unit, you learned about homogeneous mixtures, which are collections of matter containing more than one pure substance. Another name for a homogeneous mixtures is a solution.
All solutions contain a solvent, which is the substance that the remaining substance(s) in the mixture (the solute or solutes) are dissolved in. By far, the most common solvent we will encounter is water, so most or our look at solvents will focus on solutions in water (aqueous solutions).
We with begin with some definitions that will be useful in our remaining discussion on solutions. Next, we will look at how ionic solutes and how molecular solutes dissolve in water. Next we will look at reactions that can occur when two aqueous ionic solutions are combined and produce a solid insoluble product (precipitation reactions) and how to illustrate them in chemical equations. After that, we will switch gears and look at calculations involving the concentration of solutions. Finally, we will look at special classes of solutions called acids and bases before closing with solution stoichiometry, where you will build on the techniques learned in the previous chapter for mass-mass stoichiometry problems to solve similar problems with solutions.
