3 Depression Real World Application risk & benefit analysis When a solute is dissolved in a solvent, the freezing temperature is lowered in proportion to the number of moles of solute added. This property, known as freezing-point depression, is a collgative property that is, it depends on the ratio of solute and solvent particles, not on the nature of the substance itself. The equation that shows this relationship is where At is the freezing point depression, Kfis the freezing point depression constant for a particulan solvent (3.9°C kg/mol for lauric acid in this experiment and mis the molality of the solution (in mol solute/kg solvent). Assignment: Research commercial road deicing chemicals used in Northern Virginia. Consult the USEPA for the limits of these chemicals in drinking water. Produce a Risk/Benefit analysis associated with these chemicals and suggest one environmentally friendly method for deicing roads, This will be presented in the form of a paper The Paper Title Page: Will include the title (no longer than 12 words), the authors name (first MI last), the school, and the date. This information will be centered to begin 1/3 from the top of the page. The title will appear first, the author beneath the title, and the school beneath the author. Body of the Paper: There will be a page header at the top of each page that contains the title flush left and the page number flush right. mar and spelling count. The writing will contain only the third person point of view Gram It will be clear and concise, be specific not vague in descriptions and explanations, Avoid poetic languoge, you will use in text citations, no footnotes or end notes, Citation Basics: When using APA format, follow the author-date method of in-text citation. This means that the author's last name and the year of publication for the source should appear in the text, Eg. Nones, 1998) and a complete reference should appear in the reference list at the end of the paper. If you are referring to an idea from another work but NOT directly quoting the material, or making reference to an entire book, article or other work, you only have to make reference to the author and year of publication in your in-text reference.

Following correct APA format. For examples and proper use please refer to Purdue University online writing Lab (owL)(2010) Reference List: Basic Rules. from useful Information: From uc Irvine office of Research Definitions Benefit A valued or desired outcome: an advantage.Explanation / Answer
A table is made regarding the procedure/method which is assesed along with the risks involved.
1) Snow which is already melted dissolves and makes
salt into separate charged ions which can lead
to high levelsof salt ions in soil as well as water.
2) According to EPA excess ion levels
can be fatal to aquatic life.
3)Salts can also enter drinking water supplies
which can cause some serious health effetcs
due to excess accumlation of salt concentrations
in human bodies.
4)excess concentrations has impact on surrounding
habitation like plants may get dehydrated and
loose nutrients.
salts can be NaCl. MgCl, KCl
etc
