For example, if the corrected initial Brix percentage was 11.54 and the corrected final percentage was 7.69, the equation would be: 1.0000 – (0.0044993 * 11.54) + (0.011774 * 7.69) + (0.00027581 * (11.54²)) – (0.0012717 * (7.69²)) – (0.0000072800 * (11.54³)) + (0.000063293 * (7.69³)). If you are distilling alcohol at home you can test your homemade liquor for methanol to prevent the consumption of this toxic alcohol, which can cause blindness or death. 2.

For example, if the initial specific gravity was 1.046 and the final specific gravity was 1.018, then the equation would read: (76.08 * [1.046 - 1.018] / [1.775 - 1.046]) * (1.018 / 0.794).

In this test, the compound to be tested is warmed with acetic acid and a few drops of conc. A mixture of alcohol and water has much lower freezing point than that of water. If hydrogen gas is produced with effervescence, it indicates the presence of alcohols. In this test, the compound to be tested is warmed with acidified potassium dichromate solution. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/4\/4d\/Test-Alcohol-Content-Without-a-Hydrometer-Step-1.jpg\/v4-460px-Test-Alcohol-Content-Without-a-Hydrometer-Step-1.jpg","bigUrl":"\/images\/thumb\/4\/4d\/Test-Alcohol-Content-Without-a-Hydrometer-Step-1.jpg\/aid11672632-v4-728px-Test-Alcohol-Content-Without-a-Hydrometer-Step-1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":"728","bigHeight":"546","licensing":"
