What is the specific gravity of vinegar?

Answer 1

3.80373 kJ/kg K or 0.90912 Btu/lb °F

Answer 2

It depends on the 'vinegar'. Plain White Distilled vinegar is the easiest to determine. The chemical name for vinegar is 'acetic acid', and is considered to be an organic acid, as opposed to a mineral acid. The stuff that is available at your local supermarket, is supposed to be standardized. Specific Gravity is a measurement of a substance, usually a solid or a liquid, that is compared to pure water, where pure water at STP is equal to 1.00. If you have access to a digital weight scale that measures to .01 gm, with a capacity of about 2.0 kg, and a volumetric graduated cylinder, 100 milliliters in volume, then you will be able to determine the specific gravity of most liquids.

100 ml of H2O = 100.00 gm of H2O (pure water)

Anhydrous Acetic Acid, C2H4O2 , O=CH-CH2-OH, is a thick viscous liquid and is definitely heavier than water. Plain White Distilled Vinegar is a solution of water and Anhydrous Acetic Acid. A solution is 'x' amount of a substance, by weight usually, per 'y' amount of water, and is given as a percentage. In the case if distilled liquor, it is percent by volume. As such Specific Gravity is a ratio, or percentage, type of measure. You need to know the strength of the vinegar.

The real question is: Which is heavier, 100 ml of water, or 100 ml of vinegar?

If you weigh 100 ml of each, you may find that the vinegar is heavier or you may find that it is lighter than the water.

Then the calculation is simply: 'x' grams of 100 ml vinegar / 'y' grams of 100 ml water. If 'x' is larger than 'y' then SG>1.00; else if 'y' is larger than 'x' then SG<1.00.

Answer 3

According to the MSDS sheet located at http://www.skcinc.com/instructions/79893.pdf, distilled white vinegar (Acetic acid, 5% by volume) has a specific gravity of 1.01, a PH of 2.2 and is completely soluble in water.

Answer 4

The specific gravity of vinegar typically ranges from 1.006 to 1.009, depending on the concentration of acetic acid.
