General Chemistry II Exam One Main Ideas (Lecture & Online Assignments)  Electron transfer reactions  Simple ionic compounds  Ionic bonding  Polyatomic ions  Ions with some covalent bonding  Mass percent  Stoichiometry  Evaporation and concentration  Dissociation  Dissolving, dissolution  Phase changes, physical vs chemical  Solutions: solutes and solvents  Chemical change: change in chemical bonding, arrangement of atoms* o *all chemical change is also physical  Composition of solutions and concentration units  “[x]”, concentration of “x”, usually in mol/liter  Increase/decrease concentrations by changing volume  Evaporation and dilution (at constant solute)  Atomic/ionic radius trends  Ionic vs covalent bonds  Ion-dipole reactions  Aqueous solubility  Ksp- solubility product constant  General form for Ksp: AnBm  nA^+x + mB^-y  Use the equilibrium quotient, “Q” ; Q < or > Ksp  Changes in solubility with concentration (and dilution) Associated Reading  Aqueous Solubility: Ch. 12, 14, 16, 18  Equilibria and solubility curves, Ch. 16  Specifics only for Ksp, Ch. 18.5 o Table: Appendix 4  Review of solutions: Ch. 9, 12, 14  Solutions and Measurement: Ch. 14 (2, 9, 12) Occurrence of Lithium in the Environment  Lithium metal is not chemically stable in nature o Is very energetically reactive with both water and oxygen; explosive  Electron transfer reactions o Water: 2Li (s) + 2H2O (l)  2LiOH (s) + H2 (g) o Oxygen: 4Li (s) + O2 (g)  2Li2O (s)  LiOH and Li2O also are not stable in nature  Because they are strong Bronsted bases  How do we classify these chemical compounds?  Ionic Bonding: writing formulas o Li2O: (Li^+)2 (O^-2) o LiOH: (Li^+)(-OH)  Chemically stable forms for Lithium in nature o Simple salts, lithium chloride, as an aqueous solution (found in water)  Ionic formula for lithium chloride: (Li^+)(Cl^-) ; LiCl (aq) o Only one stable solid form of lithium in nature  LiAl(Si2O6) (s) ; called Spodumene o Neither LiCl nor LiAl(S2O6) can be used to make batteries  Must first be converted to Lithium sulfate or carbonate  Lithium sulfate: (Li^+)2(SO4^2-)  Li2SO4  Lithium carbonate: (Li^+)2(CO3^-2)  Li2CO3  Amongst the available Li compounds… LiCl, Li2SO4, Li2CO3, LiAl(Si2O6), which gives the most Li? o Based on molar masses, chemical bond energies, total mols of compound, mass of compound  Find molar masses of: Li2CO3, Li2SO4, LiAl(Si2O6), LiCl o 73.89, 109.94, 186.10, 42.39 g/mol, respectively o 2 mols Li in both of the first two, yet molar masses are different due to other elements o can use weight of Li divided by total weight to find %Li in the compound  mass % of Li =( mass Li/ total mass) X 100  18.78%, 12.63%, 3.73%, 16.37%, respectively  by this method, Li2CO3 is the best choice to yield more Li; Li2CO3 has the most Li by mass o yet, most of the world’s Li is still mined using LiAl(Si2O6)… why? o Why has it been so difficult to use LiCl?  Solids are easier to handle  LiCl dissolves very easily, never found as a solid  aqueous  Water has to be removed to get Li  Water sources of Li(aq)  Li in ocean  concentration  ppm  1/10^6 mg/L o Li in ocean ~ 0.17 mgLi/Lwater

"Knowing I can count on the Elite Notetaker in my class allows me to focus on what the professor is saying instead of just scribbling notes the whole time and falling behind."

Amaris Trozzo George Washington University

"I made $350 in just two days after posting my first study guide."

Steve Martinelli UC Los Angeles

"There's no way I would have passed my Organic Chemistry class this semester without the notes and study guides I got from StudySoup."

Parker Thompson 500 Startups

"It's a great way for students to improve their educational experience and it seemed like a product that everybody wants, so all the people participating are winning."
