Purpose The purpose of this lab is to mix two solutions of dissociated ions and to see if the product from the reaction is soluble or insoluble. The goal is then to create a set of solubility rules based on the findings. Experimental Methods The experiment was first started by creating a grid on which the solutions could be placed and eventually mixed. This grid was on a laminated piece of paper, each section having ample room to mix two small drops. The anions were put on the top of the grid while the cations were put down the side. This was all done on the plastic sheet that everything was mixed on. Each solution was put on the chart according to the grid. To determine solubility or insolubility, a chart was made displaying the characteristic of each box. If the resulting product had a solid precipitate, it was insoluble. On the other hand, if it remained clear, the product was soluble in the solution. The cations being studied were: K + , NH 4 + , Mg 2+ , Ca 2+ , Ba 2+ , Al 3+ , Pb 2+ , Cr 3+ , Mn 2+ , Fe 2+ , Co 2+
