Solubility of Lead(II) Bromide

The video explores the solubility of lead(II) bromide (PbBr2) in water, explaining that it is slightly soluble, leaning towards insoluble. It discusses solubility rules, highlighting that bromide ions are generally soluble except when paired with lead(II) ions. A solubility chart is used to show PbBr2 as slightly soluble, meaning only a small amount dissolves. Data is presented showing 0.455 grams of PbBr2 dissolves per 100 milliliters at zero degrees Celsius. The video concludes that for practical purposes, PbBr2 is considered insoluble in chemistry contexts.

What is the solubility classification of lead(II) bromide (PbBr2) in water?
