Determine the concentration of an unknown NaCl solution
This virtual lab activity asks you design and perform an experiment to determine the mass of NaCl
present in the solution labeled "Unknown NaCl". The stockroom contains some chemicals that you find useful.
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+].
