Lab is due October 13, 2011. You need to turn in your stamped work prelab, tables, etc. and answers to analysis items. Remember to show how you did your calculations.

 

In parts 1 and 2 of this lab, you will have the opportunity to investigate the processes of diffusion and osmosis in model membrane systems. You will also investigate.

Devon Stork DCP1: Few units are included in the measurements. Table 1. 2 contains Grams as the units, but table 1. 4 contains no units. In addition, the percentages are all percent.

 

DID YOU KNOW Osmosis is fundamental in many industrial processes such as water purification, desalination, and waste management. DID YOU KNOW Absolute zero, or zero.
