Answer:
To determine which ions will precipitate out when H2S gas is passed through a 0.5 M HCl solution, we need to consider the solubility rules for sulfides.
Solubility rules for sulfides:
1. Group 1 and ammonium (NH4+) salts are soluble.
2. Sulfides of group 2 (alkaline earth metals) and heavy metals are insoluble, except for those of calcium (Ca2+), strontium (Sr2+), and barium (Ba2+).
3. Sulfides of transition metals are generally insoluble, except for those of zinc (Zn2+) and cadmium (Cd2+).
Considering these rules, we can determine which ions will precipitate out:
A) Cd2, Fe2, Sr2:
- Cd2: According to rule 3, sulfides of transition metals are generally insoluble, so CdS will precipitate.
- Fe2: According to rule 3, sulfides of transition metals are generally insoluble, so FeS will precipitate.
- Sr2: According to rule 2, sulfides of group 2 metals are insoluble, except for those of Ca2+, Sr2+, and Ba2+, so SrS will precipitate.
Therefore, option A) Cd2, Fe2, Sr2 is correct.
B) Cd2, Hg2, Cu2:
- Cd2: According to rule 3, CdS will precipitate.
- Hg2: According to rule 3, HgS will precipitate.
- Cu2: According to rule 3, CuS will precipitate.
Therefore, option B) Cd2, Hg2, Cu2 is correct.
C) Hg2, Cu2, Fe2:
- Hg2: According to rule 3, HgS will precipitate.
- Cu2: According to rule 3, CuS will precipitate.
- Fe2: According to rule 3, FeS will precipitate.
Therefore, option C) Hg2, Cu2, Fe2 is correct.
D) Cu2, Sr2, Fe2:
- Cu2: According to rule 3, CuS will precipitate.
- Sr2: According to rule 2, SrS will precipitate.
- Fe2: According to rule 3, FeS will precipitate.
Therefore, option D) Cu2, Sr2, Fe2 is correct.
In summary:
Based on the solubility rules for sulfides, the ions that will precipitate out when H2S gas is passed through a 0.5 M HCl solution are:
- Cd2, Fe2, Sr2 (option A)
- Cd2, Hg2, Cu2 (option B)
- Hg2, Cu2, Fe2 (option C)
- Cu2, Sr2, Fe2 (option D)
