OG12 Verbal Review 54

by tarina » Thu Mar 25, 2010 10:38 pm
Tanco, a leather manufacturer, uses large quantities of common salt to preserve animal hides. New environmental regulations have significantly increased the cost of disposing of salt water that results from this use, and, in consequence, Tanco is considering a plan to use potassium chloride in place of common salt. Research has shown that Tanco could reprocess the by-product of potassium chloride use to yield a crop fertilizer, leaving a relatively small volume of waste for disposal.

In determining the impact on company profits of using potassium chloride in place of common salt, it would be important for Tanco to research all of the following EXCEPT:

A. What difference, if any, is there between the cost of the common salt needed to preserve a given quantity of animal hides and the cost of the potassium chloride needed to preserve the same quantity of hides?

B. To what extent is the equipment involved in preserving animal hides using common salt suitable for preserving animal hides using potassium chloride?

C. What environmental regulations, if any, constrain the disposal of the waste generated in reprocessing the by-product of potassium chloride?

D. How closely does leather that results when common salt is used to preserve hides resemble that which results when potassium chloride is used?

E. Are the chemical properties that make potassium chloride an effective means for preserving animal hides the same as those that make common salt an effective means for doing so?

Is there any different between D and E? They're both talking about the influence to the leather.
Why is E correct while D is not?

Good Question

There is very close difference between option (D) and (E).

D) ---> Talks about comparing the resultant leather after processing it with KCl or NaCl.
E) ---> Talks about comparing the chemical properties of KCl and NaCl.

So think, are chemical properties of salts important to compare over the resultant leather?

So it is the keyword that determines the choice. It's very clear and helpful. Thank you so much!!

I like the explanation on E
