Answer silver chloride (AgCl) and lead chloride (PbCl2).
Step-by-step explanation:
Two salts that have the same solubility at approximately 23°C are silver chloride (AgCl) and lead chloride (PbCl2).
Both AgCl and PbCl2 have very low solubilities in water at room temperature, and their solubilities are similar at around 23°C. They are both sparingly soluble salts, meaning they dissolve only to a limited extent in water to form a saturated solution.
It's important to note that solubility can vary depending on the specific conditions, such as temperature, pressure, and presence of other substances. The solubility of salts can also be affected by factors such as pH and the presence of other ions in solution. Therefore, it's always best to consult reliable sources, such as reference tables or experimental data, for accurate solubility information at a given temperature.
