Stoichiometry Lab

In class we tested if stoichiometry could predict precipitate. The materials we used were:
-a lab stand
-a funnel
-a clamp
-filter paper
-beakers
-squirt bottle
To test stoichiometry we used 3 grams of Copper(II) Sulfate and 2 grams of Strontium Nitrate. We dissolve those two in seperate beakers and mixed them together. After stirring for about 7-10 minutes we carefully poured the mixture into the filter. We diluted and continued to dissolve the leftover precipitate. When the mixture was all dissolved we put the filter paper in the dryer to leave over night
