In the potato chip part of the experiment, the petroleum ether was added to the crushed (but still solid) potato chips, whereas in the margarine analysis, the sample was first melted. Wh?
Homework Answers
The reason is that the chemical involved in the potato chips is acrylamide, which is a polar compound and the added solvent to dissolve it was hexane, which is non-polar.
Due to the unfavorable polar-nonpolar interaction, the sample was first melted in the margarine analysis.

As a food chemist for a major potato chip company, you are responsible for determining the salt content of new potato chip products for the packaging label. The potato chips are seasoned with table salt, NaCl. You weigh out a handful of the chips, boil them in water to extract the salt, and then filter the boiled chips to remove the soggy chip pieces. You then analyze the chip filtrate for Cl− concentration using the Mohr method. First you prepare...

A potato chip company makes potato chips in two flavors, Regular and Salt & Vinegar. Riley is a production manager for the company who is trying to ensure that each bag contains about the same number of chips, regardless of flavor. He collects two random samples of 10 bags of chips of each flavor and counts the number of chips in each bag. Assume that the population variances of the number of chips per bag for both flavors are equal...
