OBJECTIVES
Important Glutaldehyde Safety
Preparing Glutaldehyde Film
(Actual Mass = 0.5141g)
Preparations For Clay Exchange(Important Information and Notes About Clay)
(Such ions incldue: Al3+, Mg2+, and Fe2+ or 3+)
(Actual Mass of Clay = 2.0095g)
2.0095 g Na-MT x (92 meqv/100 g Na-MT) x (1 mol Bu3HdP+/1000 meqv) x (100/100)% x (507.65 g Bu3HdP+/1 mol Bu3HdP+) = 0.9385 g Bu3HdP+ (Actual Bu3HdP+ Mass = 0.9399g)
2.0046 g Na-MT x (92 meqv/100 g Na-MT) x (1 mol Bu3HdP+/1000 meqv) x (50/100)% x (507.65 g Bu3HdP+/1 mol Bu3HdP+) = 0.4682 g Bu3HdP+ (Actual Mass of Clay = 2.0046g) (Actual Bu3HdP+ Mass = 0.4690g) Notes |
