2- Will a precipitate be observed if 0.10 mol Ag+ and 0.001 mol SO4²- are added to make 1.0 L of solution? (Ksp = 1.4 x 10-5) yes, because Q Ksp Ono, because Q< Ksp
A sample solution contains two unknown ions. A student did a series of tests on the solution, in the order listed below. If a precipitate formed at any stage, the mixture was filtered and further tests were done on the filtrate. The results are as follows. First test:Second test:Third test:Fourth test: solution is a pink colourNaIO3(aq) added and no precipitate formsflame colour is redNa2CO3(aq) is added and no precipitate forms Two possible ions that the solution contains are a.lithium and manganese(II) b. strontium and cobalt(II) c. strontium and manganese(II) d. lithium and cobalt(II)
Calculate the concentration of dissolved sulfate ion in solution if 75.0 mL of a 0.0250 M Ba(N03)2 aqueous solution is mixed with 25.0 mL of 0.0100 M sodium sulfate aqueous solution and allowed to come to equilibrium. Ksp for barium sulfate is 1.5x10- Answer:

A student was asked to identify a compound. In an effort to do so, he first dissolved the compound in water. He found that no precipitate formed when hydrochloric acid was added, but when H2S was bubbled into this acidic solution, a precipitate formed. Which one of the following could be the precipitate? NiS AgCl HgS BaS

Part IV: Insoluble Solids Zn(OH)2 (s) Zn²+ (aq) + 2OH(aq) Zn²+ (aq) + 4NH3(aq) = Zn(NH3)4²+ (aq) Solubility of Zn(OH)2 : A. # of drops of 6 M HCI to dissolve_ B. # of drops of 6 M NH3 to dissolve Reaction 8 Mg(OH)2 (s) Mg²+ (aq) + 2OH(aq) Reaction 9 Fill in or circle your answer: A. Adding HCI to Reaction 8 causes it to shift increased/decreased. 4 25 B. Adding NH3 to Reaction 9 causes a shift in Reaction 8 and causes Reaction 8 to shift Is Mg(OH)2 soluble in 6 M HCI? 3 Is Mg(OH)2 soluble in 6 M NH3? 25 because This causes a decrease in Solubility of Mg(OH)2 : Add the same number of drops of the reagents as you did for the Zn(OH)2 and determine the effect on the solubility of Mg(OH)2. is From your observations, does Mg2+ form complex ions with NH3?
