Question

A "chemistry magic" demonstration might involve dropping red-brown pieces of copper metal into a colorless silver nitrate solutions. The resulting reaction yields grains of silver metal in a blue-green solution. Cu(s) + Ag^+ (aq) reversible Cu^2+ + Ag (s) Balance this oxidation/reduction reaction. Express K in terms of concentrations. Calculate deltaG ^ degree_ nm at 298 K. Calculate K at 298 K. Beginning with a pure silver nitrate solution of 0.155 M and adding copper until equilibrium is reached, what concentration of copper nitrate will be observed

Explanation / Answer

A "chemistry magic" demonstration might involve dropping red-brown pieces of c
