Question
A student adds solid silver chloride (AgCI) to each of two beakers: one containing 1.0 L of pure water, and one containing 1.0 L of 0.500 M NaCI. In which will AgCI be more soluble, and why? Pure H_2O: in the 0.500 M NaCI solution the chloride ions that are already present will inhibit the AgCI from dissolving by increasing the value of Q. Neither: AgCI is completely insoluble, and will not dissolve in either. 0.500 M NaCI: the sodium ions in the solution will complex with the chloride, allowing more AgCI to dissolve. 0.500 M NaCI: in the 0.500 M NaCI solution, the chloride ions that are already present will increase the amount of AgCI that dissolves by decreasing the value of Q. BothL AgCI is freely soluble in both.Explanation / Answer
AgCl is completely insoluble , and will not dissolve either
