Four U tubes each have distilled water in the right arm,
a solution in the left arm, and a semipermeable membrane between
arms.
(a) If the solute was KCl, which solution was the most
initially?
|
A |
|
|
B |
|
|
C |
|
|
D |
(b) If each solute is different but all the solutions have the same molarity, which contains the smallest number of dissolved ions?
|
A |
|
|
B |
|
|
C |
|
|
D |
Homework Answers
a)
answer : B )
b)
answer : C)
explanation:
in the tube B we can see one side higher concentration than the other it indicates KCl will have higher concentration in B
next
in C both side same level this means that there is no passages of ions from one end to other it is only possible when both side have same moalrity

- POHL Consider two solutions, A and B, both a beaker but separated by a semipermeable membrane. The membrane allows small molecules and ions to pass through, but not large molecules like polysaccharides and proteins. Solution A contains a 5% solution of glucose and albumin (a protein) dissolved in water. Solution B contains a 10% solution of sodium chloride and starch dissolved in water....

Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.01 significance level to test for a difference between the measurements from the two arms. What can be concluded?
