AP Chemistry Summer Assignment [email protected] You are to complete the following problem set prior to the first day of class in September. I will collect your answers, which should be done on separate pages because there is not enough room in this question set unless you reprint them with much more space. The difficulty of the problems varies, so don’t be surprised if you are challenged by several of them. Do give them all a good try, though. I would estimate that this problem set should take 10 to 20 hours, so please do not leave it for the last day before the start of school. You should use the text book, regents review book, yahoo answers (chemistry), mychemistrytutor.com, my website (kentchemistry.com) or any other resources you find helpful. Please also feel free to contact me at the email above if you have any questions. 1. Memorize the names, formulas and charges for the common anions . Aside from the following table, you can use Table E from the NYS reference table. Formula Ion Name Formula Ion Name Formula Ion Name 1 Charge H Hydride N 3 Azide ClO Hypochlorite F Fluoride CN Cyanide ClO 2 Chlorite Cl Chloride OH Hydroxide ClO 3 Chlorate Br Bromide C 2 H 3 O 2 Acetate ClO 4 Perchlorate I Iodide H 2 PO 4 Dihydrogen Phosphate SCN Thiocyanate NO 2 Nitrite HSO 4 Hydrogen Sulfate NO 3 Nitrate HCO 3 Hydrogen Carbonate MnO 4 Permanganate 2 Charge O 2 Oxide CO 3 2 Carbonate SO 4 2 Sulfate O 2 2 Peroxide CrO 4 2 Chromate C 2 O 4 2 Oxalate S 2 Sulfide Cr 2 O 7 2 Dichromate HPO 4 2 Hydrogen Phosphate S 2 O 3 2 Thiosulfate SO 3 2 Sulfite 3 Charge N 3 Nitride P 3 Phosphide PO 4 3 Phosphate 2.
