A sample contains Ba3(PO4)2, CdS, AgCl, NH4Cl, and ZnS. Identify the precipitate after the addition of 6 M HCl; H2S and 0.2 M HCl; and OH- to a pH of 8. Answer choices NH4Cl MnS HgS AgCl Ba3(PO4)2
Added by Tiffany A.
Step 1
After the addition of 6 M HCl, the following reactions will occur: - AgCl will dissolve because Cl- ions will form a complex with Ag+ ions: AgCl + Cl- -> AgCl2- - NH4Cl will dissolve because it is a soluble salt. - Ba3(PO4)2 will not dissolve because it is Show more…
