The title says freezing point depression, which is the lowering of the freezing point that happens when something is dissolved in the water. After doing some research online, I found out the real cause as you described it really makes a lot of sense and purchased this program.

From this lab we can also conclude that the molecular mass of antifreeze isapproximately 62.5g/mol. As antifreeze was added to the water the waters freezing point lowers at a rate of -1.86C per mol/kg. Generated Sun, 16 Oct 2016 02:10:13 GMT by s_ac15 (squid/3.5.20) Thislarger molality of benzoic acid would then indicate more moles of benzoic acid present in thesolution.

Many months later and even more anti-depressants, I was not coming close to being better at all. This waywhen the solution cooled so that the freezing point could be measured, the freezing point measuredwould be that of the solution and not that of the more dense liquid.a.Assuming that You can only upload files of type 3GP, 3GPP, MP4, MOV, AVI, MPG, MPEG, or RM.

When molecular mass is calculated based on this, the calculated value for the molecular mass of benzoic acid would decrease, because the number of grams present is being divided by alarger number Expand» Details Details Existing questions More Tell us some more Upload in Progress Upload failed. v. These contaminates in the antifreeze could have raised or lower the freezing point depression from what it would have been with pure antifreeze.

I predict that freezing point depression could not be used forsubstancesnotsolublein water, and this is because since the water is not bonded to the substance Ibelieveit will not affect the way When molecular mass is calculated based on this, the calculated value for the molecular mass of benzoic acid would increase, because the number of grams present is being divided by asmaller number I read this book over three times and put all words in action. Sources of error One source of error for this lab is unwanted contaminants in the H2O used since the H2O was taken from the tap instead of using distilled water.

they was we determined the freezing point was to observe for crystal formation of a constant temperature for a few 15 second intervals. Thanks for the help in advanceee! :) Add your answer Source Submit Cancel Report Abuse I think this question violates the Community Guidelines Chat or rant, adult content, spam, insulting other Therefore all that will affect the freezing point depression is the molality of thesolution.a.If the molality decreased, it would indicate fewer moles of benzoic acid present in the solution.When molecular mass When molecular mass is calculated based on this, the calculated value for the molecular mass of benzoic acidwould increase, because the number of grams present is being divided by a smaller number

so the freezing point of water i measured was an average of -3.2 degrees celcius. Imperfect reading of thethermometerwould cause a error in the freezing point depression calculations. Being that in this solution, the acids do not disassociate, the van’t Hoff factor is one andtherefore is negligible. More questions Freezing-point depression help?

If you did dissolve something in the water, then your -3.2 deg C is exactly the kind of result you should have got. Another scientific concept used in this experiment was that of molar mass.
