The video tutorial discusses the solubility of lead(II) sulfide (PbS) in water. It explains that PbS is generally insoluble, supported by solubility rules and a solubility chart. The video clarifies that while a very small amount of PbS may dissolve, it is largely insoluble. The tutorial is presented by Dr. B, who provides a link to a full solubility table for further reference.
