Students are preforming a lab experiment in chemistry class where they must find out what 3 mystery solutions are. The bottles are not labeled,
but one of the bottles contains NaCl, another bottle contains AgNO3, and
another bottle contains K2SO4. The students decide to mix one drop of
each unknown chemical with one drop of some known chemicals to see if
precipitates form in order to identify the unknown chemicals. Use the data
table below to determine each unknown.
