What is the chemistry behind vinegar?

Vinegar is a combination of acetic acid and water made by a two-step fermentation process. First, yeast feed on the sugar or starch of any liquid from a plant food such as fruits, whole grains, potatoes, or rice. This liquid ferments into alcohol.

Is vinegar toxic to humans?

Is there any harm in trying vinegar, though? Vinegar is fine to use on food and when mixed with water, juice, or another liquid is safe to drink. However, with a pH between 2.4 and 3.3, vinegar is acidic enough to erode tooth enamel, inflame the esophagus and stomach, and trigger nausea and acid reflux.

What is the chemical reaction between vinegar and salt?

The combination of salt and vinegar creates sodium acetate and hydrogen chloride. This chemical reaction will take an old penny and shine it like new.

What happens if you inhale vinegar?

Breathing vapours with high levels of acetic acid can cause irritation of eyes, nose and throat, cough, chest tightness, headache, fever and confusion. In serious cases damage to the airways, a fast heart rate and eye damage can occur. An accumulation of fluid in the lungs may occur and may take up 36 hours to develop.
