Question

2. The solubility of silver cyanide, AgCN, is 2.3 x 10-4 g/L at 20 °C. a. Find Ksp. b. The dose of cyanide (CN") which causes a fifty percent chance of death is 20 mg. Assume twice this amount is always lethal. Calculate the volume of saturated AgCN that would be required to produce the lethal dose. C. Could you ingest this amount by accident? (regardless of your answer to this question, I am NOT advocating this practice. Do not drink silver cyanide solutions.)
