Is PbSO4 Soluble or Insoluble in Water?

Is PbSO4 soluble or insoluble in water? The answer that Lead (II) sulfate is insoluble in water. Although it is an ionic compound, it does not dissociate into its ions in water.

These are some of the basic rules for solubility (    • Solubility Rules:  Explanation & Prac...  ):

Salts of:

Group I elements (Li+, Na+, K+, Cs+, Rb+) are
NH4+ (Ammonium ion) are soluble.
the nitrate ion (NO3-) are generally soluble.
of Cl-, Br-, and I- are soluble. Exceptions Ag+, Pb2+, and (Hg2)2+
most sulfates are soluble. Exceptions: Ba2+, Ca2+, Pb2+, Ag+, Sr2+
most hydroxide salts are only slightly soluble. Exceptions: NH4+, Li+, Na+, K+
most carbonates (CO32-) are insoluble. Exceptions: Group 1 and NH4+
Note: Rules at the top supersede any lower rules.

We can also look a Solubility Table (   • How to Use the Solubility Table / Chart  ). On the solubility table we can see that PbSO4 (Lead (II) sulfate ) is insoluble in water.

Because it is insoluble in water, we would expect that Lead (II) sulfate would NOT dissociate into its ions.

We could also just get some PbSO4 and see if it dissolves in water, that would also tell us if it is soluble or insoluble.

Based on the solubility rules and solubility chart we would expect Lead (II) sulfate to be insoluble in water. Note that a very small amount would dissolve but very little.
