Task List
- Acid Exchange for 10% clay content beads
- Wet sieving for 25% clay content beads
- Vacuum filtrate 40% clay content beads
Acid Exchange
- Vacuum Filtrate the beads
- Soak the beads in 15mL of water
- Measure the initial pH of the beads in water
- Measure the pH every 10 minute interval for 10 intervals

Notes
- Changes of pH were not visible
- We planned to decrease the amount of acid and increase the amount of water. Also, wait for a longer time for the acid exchange to happen
