4.11 In the following table, predict the identity of any precipitates formed when aqueous solutions at the intersection of each row and column are mixed. If no precipitate occurs where indicated, write "NR." Nal K,CO, LIOH H,SO, PbC2H3O2 Mg(NO3)2 AGCIO. CaCl2

(Multi answers) Find soluble compounds using the solubility rules. TABLE 9.7 Solubility Rules for lonic Compounds in Water An ionic compound is soluble in water if it contains one of the following: Li'. Na, K, Rb, Cs, NH₂ NO.C₂H₂O₂ CI. Br.I except when combined with Ag", Pb, or Hg²+ So except when combined with Ba, Pb, Ca, Sr, or Hg²+ Ionic compounds that do not contain at least one of these ions are usually insoluble. Positive lons Negative lons Select 5 correct answer(s) CuS KNO3 OKCI CaSO4 Na₂S AgCl AgNO3 RbBr BaSO4

6. The K, for the salt FeCO, is 3.07 x 10. A student mixes 500. mL of 8.2 x 10 M Fe(NO,), with 500. mL of 8.2 x 10 M Na,CO,. Calculate the molar concentrations of Fe²"c) and CO;²aq) in the 1.00 L of solution. a. b. Does a precipitate occur when the solutions are mixed, or does the solution stay clear? Explain

A precipitant will form when Mg(NO3)2 is treated with which of the following? I. K2CO3 II. NaOH III. AgNO3 Answer choices: Only I I, II, and III Only II Only III I and II

6. Explain why a saturated solution of AgCl would produce a precipitate if you added a saturated solution of NaCl (C:2)

Which anion or anions are not present in a solutionthat forms no precipitate upon addition of BaCl2 (aq)?

is silve 0.10 ANO E) 4.26 x 10-17 M 16) A solution containing AgNO3 is mixed with a solution of NaCl to form a solution that is 0.10 M in AgNO3 and 0.075 M in NaCl. What will happen once these solutions are mixed? Ksp (AgCI) = 1.77 × 10-10 A) Silver chloride will precipitate out of solution, leaving an unsaturated solution of AgCl. B) Nothing will happen since the molar solubility of AgCl is higher than the solution concentrations. 0.075 Nac! Silver chloride will precipitate out of solution, leaving a saturated AgCl solution. D) Nothing will happen since NaCl and AgNO3 are both soluble compounds. E) There is not enough information to say anything about this solution. Ksp Ag Cl 1.77 × 10-10 16)

A solution of 25.0 mL of 0.40 M H2SO4 is titrated with 0.50 M of LIOH. H₂SO4 + 2LIOH →>> Li₂SO4 + 2H₂O What volume of LiOH is required to neutralize the acid completely? Vol LiOH = [?] mL Hint: Be careful of the mole ratios! Vol LiOH (mL) Enter

A sample of 0.7960 g of an unknown compound containing barium ions (Ba2") is dissolved in water and treated with an excess of Na,SO4. If the mass of the BaSO, precipitate formed is 0.8077 g, what is the percent by mass of Ba in the original unknown compound? 00:50:42 % 9:09 PM
