2. Given the formula for the initial rate of osmosis, write the formula for the final rate of osmosis below: You will calculate the final rates of osmosis for bags 1, 2 and 3 as part of your lab report, due next lab session.
Why did some of the dialysis bags gain weight while other bags lost weight? What produced the difference in the rate of weight change among the 3 bags? Do you think there will be a difference in the initial and final rates of osmosis for any of the bags? Why or why not? What molecule was moving across the dialysis membrane to produce the weight changes observed in the dialysis bags? Experiment 3: Dialysis
The ability of a molecule to diffuse through a semipermeable membrane depends on its size and shape. The process of dialysis takes advantage of a molecule’s ability to diffuse across a semipermeable membrane in order to separate large and small molecules. In this experiment you will compare the ability of glucose and starch molecules to cross dialysis tubing, a semipermeable membrane. The dialysis tubing we are using allows the passage of molecules smaller than 14000 daltons. While you are doing this experiment keep in mind that glucose is a monomer (a single sugar molecule) and starch is a polymer made up of several sugar molecules linked together.

Many ask if the Superimploder can be installed for home use. The super soluble water the Superimploder produces (also in many cases-with the Triploder - if the water is conductive/piezo), is EXCELLENT for growth, health, washing and in fact in many cases will replace a water softener. However- particularly in a home (where a leak could cause problems) it is important the black vortex imploder nozzle be treated properly. The Imploder black vortex perfected nozzles are made of state of the art- latest Resinex Technyl (food grade) hi pressure materials and O-rings. This material is the best and strongest available, originally designed for making fittings on water meters. That nozzle has been tested at pressures up to 100psi (to be safe we recommend 80psi max). Our experience is that this nozzle will hold pressure just fine - HOWEVER- it is important to remember that mechanical torquing and bending from the installation pipe - CAN cause problems. In cases where users DO develop a crack- in their black nozzle we almost universally find- it is NOT the water pressure that caused the crack - BUT in fact the cracking is invariably caused by bending and torqing the nozzle -with stresses in the way it is installed. For example- IF the Superimploder weight is not supported properly, and even more common- if the Superimploder is connected to solid not flexible pipe in a way that pulls and torqs (twists) the nozzle. If your nozzle does develop a crack from being torq'ed by adjacent pipe connections- or to avoid this risk- we recommend connecting the black nozzle end of the Superimploder - to a FLEXIBLE hose - where feasible- which then connects to the solid pipe which can pull on the nozzle. ( we are generous about helping our users with newer Superimploders who need a nozzle replacement). - Thanks for using the most powerful water treatment for growth on the planet!
