Discussion Overview

The discussion revolves around the feasibility of creating a simple home device to indicate blood alcohol content, specifically through a chemical reaction involving sulfuric acid and potassium dichromate. Participants explore the practicality and safety of such a project in the context of responsible drinking and driving.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • The original poster inquires about a DIY method to create an alcohol indicator using chemical reactions.
  • Some participants suggest purchasing a commercial breath tester as a more straightforward solution.
  • One participant emphasizes the importance of not drinking before driving, indicating a concern for safety.

Areas of Agreement / Disagreement

Participants generally agree that commercial breath testers are available and may be preferable, but there is no consensus on the viability or safety of the proposed DIY method.

Contextual Notes

The discussion does not address the specific safety concerns or legal implications of using chemicals for this purpose, nor does it resolve the effectiveness of the proposed chemical reactions.

Who May Find This Useful

Individuals interested in DIY projects related to alcohol detection, as well as those concerned with responsible drinking and driving practices.

Hi PF,

I have been working quite heavy shifts of late being a truck driver but enjoy a few cans of beer when I can and wanted to know if there is anything I can put together at home that will give me a simple indication of my alcohol reading i.e green or red light.

How would I go about doing this?

Using the internet I found what chemicals react with each other;

In this reaction:

The sulfuric acid removes the alcohol from the air into a liquid solution.
The alcohol reacts with potassium dichromate to produce:
chromium sulfate
potassium sulfate
acetic acid
water

buy your own breath tester, they are readily available :)

Premade testers are readily available, usually around $100.
 


JUST DON'T EFING DRINK before you drive.:rolleyes:
