Question:
Why only As3+ gets precipitated as As2S3 and not Zn2+ as ZnS when H2S passed through an acidic solution containing As3+ and Zn2+ ?
Why only As3+ gets precipitated as As2S3 and not Zn2+ as ZnS when H2S passed through an acidic solution containing As3+ and Zn2+ ?
Updated On: Jun 21, 2024
- Solubility product of As2S3 is less than that of ZnS
- Enough As3+ are present in acidic medium
- Zinc salt does not ionize in acidc medium
- Solubility product changes in presence an acid
