Here's why:

* Decomposition: Silver bicarbonate readily decomposes into silver carbonate (Ag₂CO₃) and carbonic acid (H₂CO₃). The carbonic acid further decomposes into water (H₂O) and carbon dioxide (CO₂).

* Equilibrium: The decomposition reaction is an equilibrium process, but it strongly favors the formation of silver carbonate.

Therefore, you cannot find a solubility value for silver bicarbonate as it does not exist as a stable compound in solution.
