Tartaric Acid - C4H6O6

What is Tartaric Acid?

Tartaric Acid is a carboxylic acid with a chemical formula C4H6O6.

Tartaric Acid is an organic acid is found in many vegetables and fruits such as bananas, grapes, but also in bananas, citrus, and tamarinds. It is also known as 2,3-dihydroxysuccinic acid or Racemic acid. It is used to generate carbon dioxide. It is a diprotic aldaric acid which is crystalline white.

It is widely used in the field of pharmaceuticals. High dose of tartaric acid can lead to paralysis or death.

Frequently Asked Questions

Is tartaric acid a strong acid?

Tartaric acid is the acid most prescribed for modifications to the must. It is a stronger acid than malic and citric acid, and less susceptible to microorganism breakdown during alcoholic and malolactic fermentations. Tartaric acid is a potassium salt which tends to precipitate.

What is tartaric acid used for?

Tartaric acid is an essential food additive that is usually mixed with baking soda in recipes to serve as a leavening agent. It can be used in all food types except untreated foods. Tartaric acid occurs naturally in plants such as grapes, apricots, oranges, bananas, avocados, and tamarinds.

What is the difference between tartaric acid and citric acid?

Tartaric acid and citric acid are two types of plant acids which are used as natural additives to food. Tartaric acid as well as citric acid, are also antioxidants.

Is tartaric acid strong or weak?

Only a few acids are rated as solid. Many of the organic acids present in wine are low acids. Many weak acids are therefore stronger than others. Tartaric acid is a weak acid, and about one out of every 900 molecules of tartaric acid ionize in water.

What is tartaric acid found in?

Tartaric acid is an organic white diprotic, crystalline acid. The compound naturally occurs in many plants, particularly in grapes, bananas, and tamarinds. It is also one of the wine’s primary acids.
