Objective Acid Exchange for yellow beads Wet Sieving for 10% Beads Vacuum Filtrate 40% Beads Wet Sieving Description Vacuum filtrated 25% beads with acetone. (Beads still stuck together though less than with water) Run size analysis on 25% beads wet to figure out which filters to use Will attempt to vacuum filter by size Yellow Beads in acid at equilibrium pH: 10%: 0.915 25%: 0.901 40%: 0.936 Mass of vacuum filtered beads +125mL containers: 10%: 32.544g 25%: 32.247g 40%: 33.271g Data Table 1: Data for acid exchange of beads Minute pH of 10% clay content pH of 25% clay content pH of 40% clay content 0 3.419 3.161 2.773 10 3.209 3.002 2.489 20 3.176 2.901 2.383 30 3.150 2.844 2.373 40 3.093 2.824 2.376 50 3.060 2.791 2.375 60 3.024 2.793 2.360 70 2.995 2.758 2.355 80 2.985 2.764 2.355 90 2.959 2.766 2.359 100 2.941 2.734 2.312 Notes
