Post$-$Lab Question $7$

Recall that you are on the board of trustees for a Wisconsin township that frequently experiences winter temperatures of $-16C.$ You are responsible for ensuring that the city's $30,000$ residents are able to travel safely in even the coldest and iciest conditions. You must decide if the city purchases the pre$-$prepared ice melt blend or proposes a new blend for use in winter next year. You must consider environmental impact, lowest effective temperature, cost, and your experimental results in your decision. Of note, the pre$-$prepared blend would simplify logistics for the city, but the company's price includes a $$\frac{5}{?}$ ton mixing fee; if you create your own blend, the cost would simply be calculated from next winter's projected prices of pure compounds in Table FPD$.1$ plus the $$5/$ton mixing fee.

Would you recommend the city purchase the pre$-$prepared blend or change the percent composition of blended ice melt? Regardless of which choice you recommend, you must include the following in your response:

Percent composition for your recommended ice melt

Price per ton $($You do not need to show your work$)$

Why this ice melt is ideal from an environmental impact perspective

Will the lowest effective temperature meet the needs of the Wisconsin township?

You do not need to calculate a new lowest effective temptrature.

Use your experimental results to support your response.
