There is lots of breath analyzers but how do I actually really know (except for reading the label-if provided) how much alcohol % is really in alcohol.? Can or do alcohol makers actually cheat on us? How and where can I get or even make my own tester?Does anybody know? Asked by Peter - Wed Jun 14 04:02:51 2006 - - 6 Answers - 0 Comments A. There is a product called a hydrometer. Your best bet to find one would be to look on homebrew webages. They're relatively cheap. There is a specific hydrometer called a "alcoholometer" (seriously). That's probably going to be the one you want. Answered by ridesonroces - Wed Jun 14 04:22:53 2006 Eep...chemistry? Q. 8. The police often use a device called a breath analyzer to test drivers suspected of being drunk. The chemical basis of this device is a redox reaction. A sample of the driver s breath is drawn into the breath analyzer, where it is treated with an acidic solution of potassium dichromate. The alcohol (ethanol) in the breath is converted to acetic acid and the chromium VI ion (orange-yellow) is oxidized to the chromium III ion (green). The drivers blood alcohol level can be determined by measuring the degree of the color change using a colorimeter (spectrophotometer) built into the device. Balance the reaction that occurs in this device according to the following equation: (Remember the charge difference is per atom) C2H5OH + … [cont.] Asked by stylinpat - Mon Oct 29 23:05:04 2007 - - 1 Answers - 0 Comments A. in C2H5OH ---> HC2H3O2 each carbon changes from -2 each into zero each , a change of 2 per carbon... a change of 4 per C2H5OH in K2Cr2O7 --> Cr2(SO4)3each Cr changes from +6 each to +3 each, a change of 3 for each Cr... a change of 6 for each K2Cr2O7 the ratio is 6 C2H5OH + 4 K2Cr2O7 + etc which reduces to 3 C2H5OH + 2 K2Cr2O7 + etc first balance the C's, Cr's & K's then balance the SO4's then H's last the oxygen are the check on your work 3 C2H5OH +2 K2Cr2O7 + 8 H2SO4 -->3 HC2H3O2 +2 Cr2(SO4)3 +2 K2SO4 +11 H2O Answered by Steve O - Tue Oct 30 01:00:53 2007 Oxidation and reduction?
Q. The question is that the legal limit of alcohol is 0.08% w/v and a driver blows 25ml of air into the breath analyzer and 7.5ml of 0.0991 M K2Cr2O7 are needed to completely titrate the ethanol is the driver guilty of impaired driving? What I got was the number of moles of K2Cr2O7 and from that I got a mass by multiplying the moles by the molar mass and multiply by 100. I'm wondering if I did this right or if I have to multiply by 3 because the ration of ethanol to K2Cr2O7 is 3 to 2. The chemical equation is 3CH3CH2OH + 2K2Cr2O7 + 8 H2SO4 >> 3CH3COOH + 2 Cr2(SO4)3 +2 K2SO4 +11H2O Asked by kaykey - Sat Nov 10 11:42:13 2007 - - 2 Answers - 0 Comments A. Lancenigo di Villorba (TV), Italy Yes, this results a Oxidimetric Determination. In effects, Potassium Dichromate results involved in a redox reaction giving off Ethanal in non-aqueous media 3 CH3CH2OH(aq) + K2Cr2O7(aq) + 4 H2SO4(aq) ---> ---> 3 CH3CHO(aq) + Cr2(SO4)3(aq) + K2SO4(aq) + + 7 H2O(aq) or Ethanoic Acid in aqueous media as in your case 3 CH3CH2OH(aq) + 2 K2Cr2O7(aq) + 8 H2SO4(aq) ---> ---> 3 CH3COOH(aq) + 2 Cr2(SO4)3(aq) + 2 K2SO4(aq) + + 11 H2O(aq) Now, I can execute calculations about dichromate 7.5E-3 * 9.91E-2 = 7.43E-4 mol K2Cr2O7 which have to be corrected to Ethanol Chemical Equivalents CH3CH2OH : K2Cr2O7 = 3 : 2 so I obtain 7.43E-4 * 3 / 2 = 1.11E-3 mol CH3CH2OH or in mass-term (e.g. Ethanol's Molar Mass as… [cont.] Answered by Zor Prime - Sat Nov 10 12:02:16 2007 From Yahoo Answer Search: "Alcohol Analyzers"
