Was the membrane-tubing-permeable to starch?
I'm assuming this is in reference to an experiment where you put a starch in dialysis tubing, and then put iodine in surrounding solution. Dialysis tubing has a limit of roughly mwco (molecular weight cut off of 10,000). Iodine has a molecular weight of roughly 126, so it can pass through. On the other hand, starch is a polymer of 1000's of glucose molecules. Glucose (C6H12O6) has a molecular weight of roughly 180. 1000 * 180 = 180,000, so glucose cannot pass through the dialysis tubing. In this experiment you should see the sealed tubing turn purple-pinkish after the iodine diffuses through. The outside solution should remain the same color.
What is a rubber stopper used for in chemistry?
Rubber stoppers are widely used for the commercial, industrial and scientific markets. They are made from different types of rubber and available in various sizes and styles depending on applications.What are Rubber Stoppers used for?Possible uses of rubber stoppers are wide and varied such as :Mechanical StopBumpersVibration MountGrippersClampsSticky feet for platformFits into Test Tubes, Boiling FlaskPipe stoppersPaint masksTube plugsDoor stopperThe kind of rubber stopper used in chemical laboratories is a plug which fits into the top of a test tube or flask, often with a hole or holes bored in it for the insertion of a piece of glass tubing. They used to be made of cork but rubber is less likely to disintegrate and get into the contents of the flask or tube.

What arethe Uses of clay shield and rubber tubing?
The clay shield and rubber tubing are useful in heating during experiments. The rubber tubing connects the Bunsen burner to the gas outlet. The tubing enables the water to cool as it flows through the condenser during the distillation process.
Why should the end of the glass tubing be fire-polished?
Foremost for safety to prevent injury to users but also to alow smooth connection when using tubing of rubber stoppers
What are the safety precautions and techniques when inserting a glass tubing in a rubber stopper?
never attempt to insert glass tubing that has a jagged end, all glass tubing should be fire polished before its inserted into a rubber stopper. Use water or glycerin as a lubricant at the end of the glass tubing before inserting it into the rubber stopper. ask teacher for proper lubricant. Protect hands and fingers by wearing leather gloves or placing a folded cloth between your hands and the tubing. hold it as close as possible to the part it is inserted to the rubber stopper. always point the tubing away from the palm of your hand that holds the stopper. use a twisting motion and push the tubing into the stopper. At the end of the experiment put on leather gloves or place the folded cloth between your hands and the tubing and remover the stoppers from the tubing to keep them from sticking to the glass. if it wont budge, use lubricant.
