Chemistry students did an experiment that identified an unknown solution. They set up a spot plate with 6 ionic solution and how they reacted with each other. When two colorless solutions are mixed and a white cloud is formed, this is a double displacement reaction. In this experiment, of the 15 reactions, only 6 formed precipitates. They tested their unknown with the same six solutions and using the way they reacted and comparing with their standards, they could identify their unknown.
