Molarity Lab Day 1

This was actually a very fun and interesting lab. We have to solve a murder case (of course, fake one). We were given an unknown solution and 5 suspects. We have to create a procedure to determine the identity and molarity of the solution. All this was on Monday. Today, we did the procedure. In the procedure, we had to first determine the identity of the unknown solution by mixing it with Na2CO3. If a precipitate formed, the solution was AgNO3. If it didn't form a precipitate, it was KI. Then we mixed all of the solutions in a beaker. Then we massed the filter paper and used a funnel to filter out the crystals. That was it for today.
