Speaking of tartaric acid, perhaps many people will be full of questions, because this is generally professional qualitative problems, so like people are not understand, and a. Not in the lives of ordinary people
It makes more sense to hit it. But sometimes we listen to it in a context
To tartaric acid, but may be derided as ignorant for not knowing it,So we have to constantly learn new knowledge.
Tartaric acid is an acid, and tartaric acid is found in many plants, like our summer
Tartaric acid is found in grapes that are often eaten. But just saying that,
A lot of people don't understand it very well. So, here is a good detailed introduction

What tartaric acid really is?

L-tartaric acid is an organic compound with the molecular formula C4H6O6. Widely used as a souring agent in beverages and other foods, used in wine, soft drinks, candy, bread, some gelatinous sweets.
Historically, tartrate has been instrumental in establishing organic stereochemistry. In 1769 scheele first obtained free colorless tartaric acid crystals from the fermentation liquid of grape juice. Its various stereoisomers and racemes have different physical properties. The natural existence of more dextral, especially in grape juice and other pulp juice, it is also called fruit acid. If butenic acid is used to control oxidation, the racemate is obtained. The tartrite produced in the above reaction process is treated with lime milk to produce calcium tartrate and then acidified to get meso.
 
In 1848, When The French chemist Pasteur was engaged in the study of ammonium sodium tartrate crystalology, he saw an interesting phenomenon that had not been noticed before: ammonium sodium tartrate without optical rotation was a mixture composed of two different crystals. Their shapes were mirror images of each other, and they were actually racemes. He used a magnifying glass and tweezers to carefully divide the mixture into small piles. A bunch of them are dextral, a bunch of them are left-handed, and they're like a bunch of them are right hand gloves, and a bunch of them are left hand gloves. Both piles of crystals in water are optically active. He first discovered the relationship between molecular stereoisomerism and optical rotation, and proposed the concept of enantioisomerism, which laid the foundation for the development of organic stereochemistry.
Tartaric acid is often used in medicine, mordants and tanning agents are also commonly used as reagents for the separation of racemate basic compounds. It is also the acid agent in food additives, acid feeling is better than malic acid, lactic acid and so on. Several of its salts have important applications. For example, potassium sodium tartrate was used in laboratory to prepare Phelan reagent for the identification of aldehyde functional groups in organic molecular structures. Its potassium-sodium salt, also known as Rochelle salt, polarizes its crystals under pressure so that the two surfaces produce a potential difference (piezoelectric effect), which can be made into piezoelectric elements, used in radio and cable radio receivers and pickups. Potassium antimony tartrate (commonly known as tartar emetic) is used medically to treat schistosomiasis.
