Question

Use the solubility table to answer the following. You do not need to mix any chemicals. 1. Circle the following compounds if they will not dissolve completely or will form ppt in H a CaSO4 (s) Cu(IO3)2(s) AgNO3(s) Baco3 (s) Pb(NO3)2(s) Al(OH)3(s) 2. circle all of the following solutions that will form a precipitate with addition of Mg(IO3)2 aq) Ba (NO3)2(aq) Pb (NO3)2(aq) K2CO3 (aq) CuCl2(aq) NH40H (aq) ZnSO4(aq) 3. Circle all of the following solutions that will not form a precipitate with addition of Ag2so4 KOH (aq) BaCl2(aq) Pb(NO3)2(aq) K2CO3(aq) Cu (NO3)2(aq) NH4NO3 (aq) 4. write the precipitate(s) that will form and remain when the following solutions are mixed excess NaOH (aq) CaCl2(aq) Al2(SO4)30 ppt(s) excess H2SO4 (ag) Pb(NO ppt(s) 5. A student divides an unknown compound into three test tubes and performs these tests: When excess Pb(NO3)2 is added to the first tube there is a precipitate When Kacoa is added to the second tube there is a precipitate When excess Klos is added to the second tube there is a precipitate The compound could be (1 only): Mg (NO3)2 ZnSO4 Ba(OH)2 NaCl (NH4)2CO
