1. Write the chemical formulas for all the barium salts that can be formed in Part 1 Part 1A: Solubility of barium salts under neutral conditions 1. Using a clean disposable pipet, transfer 1 mL of Co-anion solution to a clean test tube and label the test as “Co?- neutral”. Repeat this for the remaining anion solutions S0?-?,P03-?, NO3″,C1-7,7- ‘so that you will have six test tubes with six unique anion solutions. Use a different pipet for each anion solution, so as to not cross contaminate. 2. Next, add drops of 0.1 M BaCl2 to determine which of the anions will react with Ba2+ii to form a precipitate or insoluble barium compound under neutral conditions. Stir the solution well after addition of each drop. Record the number of 0.1 M BaCl2 drops needed to initiate formation of a precipitate (insoluble solid). Record the color of each precipitate and the amount of the precipitate as copious, moderate, or sparse. 3. If adding 5 drops of 0.1M BaCl2 does not cause a precipitate to form, we can assume that at a water soluble barium salt was formed. Record this observation (no ppt formed). 4. Next, determine if a precipitate will form if the pH is adjusted from neutral pH to acidic pH by adding 3 drops of 6 M HNO3 to each test tube that has a precipitate. Stir the solutions well and record your observations. Is the precipitate soluble under acidic conditions? Compounds Containing the Following Ions Are Generally Soluble Li”, Na, K, and NHA NO3 and C2H302 CI”, Br, and I Exceptions None None When these ions pair with Ag , Hg22t, or Pb2+, the resulting compounds are insoluble. When Soc? pairs with Sr2+, Ba2+, Pb2+, Ag, or Ca?”, the resulting compound is insoluble. SO Compounds Containing the following Ions Are Generally Insoluble OH and S? Exceptions When these ions pair with Lit, Na, K, or NH4, the resulting compounds are soluble. When S2 pairs with Ca? , Sr2t, or Ba?, the resulting compound is soluble. When OH pairs with Ca²+, Sr2t, or Bałt, the resulting compound is slightly soluble. When these ions pair with Lit, Na, K, or NH4, the resulting compounds are soluble. CO,? and PO,
