Abstract:
The average permeability constant of potassium chloride through Fisher
Scientific #21-152-18 dialysis tubing is found to be 0.00063 ± 7.63E-05
(95% CI). The precision of the seven trials was 13.1%. Because literature
values were unavailable, accuracy had to be determined by another method.
Given this method, the accuracy was determined to be 2.54%. However,
the seven trials conducted yielded significantly different permeability
constants. Statistical differences were concluded from t-tests
and non-overlapping 95% CI. Although initial concentration of KCl
solution inside the membrane was not expected to affect the permeability
constant, the results show the contrary. The unexpected results and
the presence of no trends between any trials indicate that a complex mechanism
must be affecting the diffusion of KCl through the membrane
