Final answer:
None of the provided circumstances will result in the complete dissolution of AgCl in pure water, though raising the temperature slightly increases its solubility. The correct answer is b.
Step-by-step explanation:
The ability of a sample of solid AgCl to dissolve completely in pure water is based on its solubility, which is influenced by temperature and pressure. According to the solubility guidelines, AgCl has an extremely small solubility even at higher temperatures (1.33 × 10-5 M at 25°C).
However, pressure has negligible effect on the solubility of solids in liquids. Given that the solubility of AgCl is very small even at high temperatures, none of the options presented (a, b, c, or d) would result in complete dissolution of AgCl in pure water.
However, the solubility can be increased slightly by increasing the temperature (44. Only (b)), so the closest option here would be (b) High temperature and high pressure, although it is understood that pressure has little effect on the solubility of a solid in a liquid.
