==Swelling capacity of beads== | |||
* Vacuum filtrate the beads. Weigh them before and after | |||
** Vacuum filtration did not dry the beads thoroughly enough. | |||
** Beads were placed in acetone to further remove water | |||
* 10% clay content | |||
** Mass of wet beads: | |||
** Mass of dry beads: 176.58-173.66 = 2.92 g | |||
*** Swelling capacity = (176.58-173.66) | |||
* Place dried beads in 0.1M HCl | |||
** Measure pH | |||
** Let them sit till Wednesday to find change in pH | |||
*** 10%: pH = 0.933 | |||
*** 25%: pH = 0.901 | |||
*** 40%: pH = 1.040 |
