To solve the question of which sulfide is insoluble in dilute acids but soluble in alkalies, we can follow these steps: ### Step 1: Understand the properties of sulfides We need to determine the solubility of the given sulfides in dilute acids and alkalies. The sulfides we are considering are PbS (lead sulfide), CdS (cadmium sulfide), FeS (iron sulfide), Sb2S3 (antimony sulfide), and S3 (which seems to be a typographical error, as it is not a known sulfide). ### Step 2: Analyze each sulfide 1. **PbS (Lead Sulfide)**: This sulfide is generally insoluble in both dilute acids and alkalies. 2. **CdS (Cadmium Sulfide)**: This sulfide is also insoluble in dilute acids and alkalies. ...
