What is the solubility of technetium?

Technetium can exist in various oxidation states, leading to different solubilities depending on its chemical form and the surrounding conditions. Generally, technetium tends to be more soluble in its lower oxidation states (e.g., Tc(IV)) compared to higher oxidation states (e.g., Tc(VII)). Technetium can form soluble pertechnetate (TcO4-) and colloidal species under certain conditions.
