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
    • pH of water = 6.593
