Answer Questions 1 and 2 and SHOW ALL WORK please.

In Task 2 of Project 4 you are to design a series of superabsorbent pads/pillows for the efficient clean-up of heavy metal ion solution spills. The dea is to build small-sca proof of conce pt" prototypes that can be conve tly and economically tested on the ben ch so that you can nd or trends in your pad/pillow design dentify series that can be used to quantitatively predict the behavior of the pad/pillow beyond the a tre range of conditi ons or designs tested (THINK GRAPHS o accomplish th must put some tho ught into what variable or variables are is, you relevant to your design. Obviously, you will need to build a set of small-scale "proof of concept prototypes the prototype pad/pillow dimensions must not exceed 8 cm X 8 cm. your pad/pillow designs are limited to the follow materials Cost/Unit H20 Permeability Water absorbent-significant Opaque white granular sodium polyacrylate $0.079/g water absorption Micro-punctured 1.6 mm x10 Insoluble i Directional H20 permeability due opaque black flexible 0.028 to "micro-funnels" (micro-pores) polypropylene sheets Spun-bonded polyester Water permeable due to fibrous Fibrous grey stiffsheet. $0.037 sheets Filter Paper Sheet Water permeable due to open 0.015 Spun polyester fill $0.012 Polyethylene liner Water impermeable flexible sheet Note that spun-bonded polyester sheets must be thoroughly rinsed in running D.I. water to release polymer fines and other dust. Failure to do that is not compatible with abso spectroscopy (the baseline absorb will be very this will result in a turbid to translucent solution gh spill Further you must design a test procedure to evaluate your prototype(s), where the "test must be 50 mL of a solution 0.05 M in Co(NO, and Cu(NO (Cu and Co2 will serve as surrogates for more toxic heavy metal ions). The test procedure must include a means to quantify the mass of Cu and Co absorbed.
