Interpretation Introduction To explain: What determines the number of significant figures in the result while adding or subtracting the measured quantities. Explanation For addition and subtraction, look at the decimal portion (i.e., to the right of the decimal point) of the numbers only. Count the number of significant figures in the decimal portion of each number in the problem (consider only the digits to the right of the decimal). Add or subtract the numbers as required. Round off the answer to the least number of places in the decimal portion of any number. Thus, for the calculations which involve only addition and subtraction, the final result carries the same number of decimal places as the quantity with the least decimal places...

Briefly differentiate between chemical potential and electrochemical potential.

According to open access forums ionic antimony Sb (111) can be reduced to elemental Sb (0) in solution and in macromolecules like condensation polymers polyethylene terephthalate (PET) causing greying of the polymer matrix. It has been connected to thermal degradation of the polymer during processing to the formation of thermally unstable EG ethyleen glycol that forms at various temperatures formic acid, formaldehyde, acetaldehyde and much more depending on temperature. I need to know what organics are more powerful reducing agents and at what concentration (relative) to each organic will initiate this reduction. Furthermore, is the pH dependant ? Are other trace elements in the plastic also a cause of concern e.g. aluminum from aluminum chloride (lewis acid). Therefore, the ultimate solution should include a means to inhibit reduction of ionic antimony and will the same solution comply with cobalt impurities from ionic cobalt? Some PET have combinations of catalyst and their residues…

From a pH standpoint is the reduction of ionic Antimony Sb (111) to elemental Sb (0) occur more readily by acidic species acting as reducing agents or basic substances? I want to inhibit this reduction of ionic to elemental. Suggestions and directions!
