Sept. 25 - Physical and Chemical Changes LAB

Congratulations on completing the laboratory investigation!  The class did well and we only had one minor spill in period 4 which was safely and promptly cleaned up.  You have all now safely worked with hydrochloric acid!  Here's a video of the same reaction that you all witnessed in class today, only they used a slightly different procedure:
