Student investigate which antacid is the most effective in neutralizing hydrochloric acid. This lab is set up in the ADI style, but simplified to be more accessible to my on-level 10th grade chemistry students.
Day 1: Background, Pre-Lab & Write Procedure (25%)
Day 2: Complete the lab & collect data (25%)
Day 3: Poster (25%) - group assignment
Day 4: Lab Report (25%) - individual assignment
For this lab you will need 1.0 M HCl, Universal indicator (or pH probes), Alka-selzer, Tums, Rolaids, Gavison and Baking Soda (or other antacids, white tablets work better). You could also use a mortar and pestle to grind the antacids, but it's not required.
I use this as a Google Doc, have students make a copy and share with their group and me. This Word document is editable : )
