Soluble and insoluble salts
|Most sulfates||Lead sulfate, barium sulfate and calcium sulfate|
|Most chlorides, bromides and iodides||Silver chloride, silver bromide, silver iodide, lead chloride, lead bromide, lead iodide|
|Sodium carbonate, potassium carbonate, ammonium carbonate||Most other carbonates|
Keeping this in consideration, is lead sulfate a precipitate?
Adding a source of aqueous sulphate ions to a solution of lead(II) nitrate results in a white precipitate of lead(II) sulphate. The easiest thing to add is usually dilute sulphuric acid - but any other soluble sulphate would do.
Is PbSO4 a salt?
A very soluble ionic salt (e.g., NaCl) dissolves and completely dissociates into Na+ (aq) and Cl- (aq). However, some salts are only slightly soluble, and an equilibrium exists between dissolved and undissolved compound. Consider the addition of PbSO4 (s) to water.
Why lead sulphate is insoluble?
There are many exception in the solubility of lead salts like: Lead sulfate is insoluble in cold water whereas most of the sulfates are soluble in cold water. Lead chloride is also insoluble in cold water but is soluble in hot water. Carbonates are generally insoluble in water but they dissolve in dil.
