Today in class we did a lab to determine if stoichiometry can accurately predict the mass of produced chemical reactions. In the experiment we dissolved 2g of Strontium Nitrate in 50ml of water. Then we dissloved 3g of Copper Sulphate in 50ml of water and combined the two solutions together. We created a precipitate (Strontium Suplhate and Copper (II) Nitrate). After mixing the solutions the precipitate will be separated by filtration, dried and weighed.

Next class we will be finishing up our lab by weighing our dried filter paper with precipitate.
