Murder Lab Reflection

I actually really liked the Murder Mystery Lab. The calculations were fairly straightforward, the lab work wasn't too tedious, and the chemistry involved isn't too complicated to understand. The only thing I can complain about is how long it took to write out the procedure and such.

Molarity Lab

Today we started the molarity lab in class. In this lab, we have to figure out the poison used to murder Miss Scarlet, using a variety of chemistry concepts along the way. Today, we conducted reactions using silver nitrate and sodium carbonate. Later we will measure the mass of the precipitate formed in this reaction to find the molarity of the murder weapon.

Good to the Last Drop

Today we took notes on dilutions and did a lab where we started with an initial solution of 10 milliliters of water and 20 drops of food coloring. We then took one milliliter of the initial solution and diluted it with 9 milliliters of water. We then repeated the steps using each subsequent solution as the initial.
