Question

VIL, Logical Solubility Problems Use the solubility tables to answer the following. You need not mix any chemicals. Circle all of the following solutions that will precipitate with addition of BaCl (aq)? KNO(aq) (AgNO(aq Circle all of the following compounds that will not dissolve completely (leave a pp) in Hi Olag) Cirele all of the following solutions that will precipitate with addition of MgSoda)? Write the precipitate(s) that will form and remain when the following solutions are mixed: AgNOs(aq) + ZnClz(aq) + excess NaOH (a?) ppt(s)-Ant CA A student divides an unknown compound into two test tubes and makes these tests: When CuCz is a added to the first test tube there is no precipitate When excess H2S04 is added to the second test tube there is a precipitate: The compound could be (l oaly: PONO KCOs BaC2 Fe(S04)

Explanation / Answer

* Solutions that will form precipitate with BaCl2 solution:

(NH4)2CO3 (aq), CuSO4 (aq)

* Solids that will not dissolve in concentrated H2SO4 are:

PbSO4 (s), BaCl2 (s)

* Precipitation with MgSO4 (aq): Pb(NO3)2 (aq)

* Precipitates are:

First reaction: AgCl

Second reaction : Ag2CO3

*

The solution contains BaCl2
