Why does it take longer for maltose to escape from visking tubing?

You do not give anything to compare the maltose to, but I assume you mean 'longer than glucose'.
Glucose is a monosaccharide, that is it consists of a single ring of carbon and oxygen atoms. Maltose is a disaccharide, that is two glucose rings joined together. That makes it almost twice as big as glucose. If the particles of the two sugars are at the same temperature, they have the same average kinetic energy, so the more massive ones move more slowly. The slower movement means maltose diffuses more slowly out of the tubing.

What will and won't pass through a visking tube?
Cannot pass through visking tubing: sugar starch lactose sucrose Can pass through visking tubing: Iodine Glucose Maltose
Can salt pass through visking tubing?
yes it can
What is a type of tube that is semi-permeable?
visking tubing
Why it was important to wash the outside of the visking tubing?
it needs to dry
What part of the human body acts a the visking tubing?
capillaries in the villi
Why could glucose could pass through the visking tubing?
Because it has starch in it.
How does a visking tubing differ from a cellmembrane?
Visking tubing contains millions of tiny holes which only let small molecules, like water, diffuse through. Large molecules, such as starch, cannot cross the membrane. We say it is partially permeable (permeable means a substance is able to pass through). This is similar to a cell membrane. Visking tubing can therefore be used as a model of a cell.
What is visking tubing?
Visking tubing is a kind of seamless semi permeable tubing, a cellulose tubing, that is made of regenerated cellophane. It is used as an edible casing for sausages or as a membrane in dialysis.
Can starch pass through visking tubing?
We supply Visking tubing and offer the following information: The molecular weight cut-off of this product is 12000 - 14000 daltons. This means in theory that molecules larger in MW than this will not pass through the membranes and ones smaller will. Starch has a very high molecular weight and the tubing is often used to illustrate the effect of enzymes breaking starch down into to simple sugars. Starch therefore should not pass through the membrane wall. The user of this product should be aware that this is a nominal cut-off and long thin molecules above the 14kd cut-off may go through and globular molecules below may be retained. In addition the charge on a molecule may effect the rate of transfer across the membrane.
What part of our bodies acts like a visking tube?
You may be thinking of the blood capillaries. Like visking tubing, their walls are able to let substances diffuse in and out. This is also true of the cell membranes. However both of these are much more permeable than visking tubing. The kidney contains semi-permeable membranes which allow urea to pass through but not other substances such as proteins.
Why must rinse the outside of the Visking tubing thoroughly with water?
so as to prevent contamination. that should be one point.
What can you use as alternative to visking tube?
the visking tubing is useless and we need an alternative. can u helpful human beings help please? we are in the middle of a chaotic crisis trying to find the reason for osmosis. please help you kind human beings :) i hate you bye -from the scientists of Mars :
