For this activity, the solution viewer in the virtual lab shows only the concentration of silver ion (Ag*) in the selected solution. This mimics a common experimental situation. Techniques such as spectroscopy or electrochemistry often make it easy to measure the concentration of only a single species, such as Ag*. Chemists must then design experiments that meet their goals, while collecting data only on the concentration of that species. In this activity, you must determine the amount of NaCl in an unknown solution, using measurements of [Ag*]. The Ksp for Silver Chloride is: 1.830e-10.
