What Is The Solubility Of Silver Perrhenate?

Silver perrhenate is a salt composed of silver cations (Ag+) and perrhenate anions (ReO4-). Its solubility depends on the specific conditions, such as temperature and solvent.

At room temperature, silver perrhenate has low solubility in water, with a reported solubility of 0.016 g/100 mL. This means that only a small amount of silver perrhenate will dissolve in water to form a saturated solution.

However, the solubility of silver perrhenate can be increased by heating the solution. For example, at 100°C, the solubility of silver perrhenate in water increases to around 2.3 g/100 mL. In general, the solubility of most salts increases with temperature.

Furthermore, the solubility of silver perrhenate can also be affected by the presence of other ions in the solution. For instance, the presence of chloride ions (Cl-) can decrease the solubility of silver perrhenate in water due to the formation of insoluble silver chloride (AgCl) precipitate. Conversely, the presence of nitrate ions (NO3-) can increase the solubility of silver perrhenate due to the formation of soluble AgNO3 compound.

Overall, the solubility of silver perrhenate varies depending on the specific conditions, but it generally has low solubility in water at room temperature and can be increased by heating or affected by the presence of other ions in the solution.
