Is ascorbic acid an organic compound?
Ascorbic acid, also known as vitamin C or L-ascorbic acid , is a naturally occurring organic compound with antioxidant properties. Ascorbic acid is found in plants and food, including citrus fruits, tomatoes and green vegetables.
Is ascorbic acid a pure substance?
Pure vitamin C is a white, crystalline solid that is soluble in water and ethyl alcohol. Its chemical name is ascorbic acid. The oxidation of vitamin C, ascorbic acid, is brought about by the loss of two hydrogen atoms as the vitamin is converted to dehydroascorbic acid.
Is vitamin C an element?
Unlike dietary minerals, which are elements on the periodic table, vitamins are molecules made from the elements. Vitamin C (ascorbic acid), for example, is made of carbon, oxygen and hydrogen and is found naturally in nature and can be produced by many animals – but not humans, fruit bats or guinea pigs.
Is alcohol a homogeneous mixture?
Most wines and liquors are homogeneous mixtures. The science of making wine and liquor is based on employing ethanol and/or water as a solvent on various substances – charred oak for bourbon whiskey, for example, or juniper in gin – to create unique flavors. Water itself is an example of a homogeneous mixture.
Is perfume a homogeneous mixture?
A example of a homogeneous mixture is perfume.
Is ascorbic acid the same as L-ascorbic acid?
Vitamin C and ascorbic acid are 100% synonymous. Both are L-ascorbic acid. The L stands for its specific 3D structure. The name ascorbic acid is derived from the term “anti-scurvy acid”.
Is ascorbic acid a strong acid?
Ascorbic acid is a weak acid (pKa= 4.2) [3], only slightly stronger than vinegar. When dissolved in water, vitamin C is sour but less so than citric acid found in lemons and limes.
Is ascorbic acid the same as L ascorbic acid?
What is the pH of ascorbic acid?
Aqueous solutions rapidly decay in air and light and have a maximum stability at pH 5.4. Melting point in a capillary tube: approximately 190 °C with decomposition. Ascorbic acid in aqueous solution has a pH of less than or equal to 3.
Is vitamin C the same as ascorbic acid?
Most food supplements contain vitamin C in the form of ascorbic acid. This is the proper name for vitamin C and the form found naturally in foods.

Where can you find vitamin C or ascorbic acid?
Ascorbic acid, also known as vitamin C or L-ascorbic acid , is a naturally occurring organic compound with antioxidant properties. Ascorbic acid is found in plants and food, including citrus fruits, tomatoes and green vegetables. It has other applications in photo development and in some specialized scientific applications.
Why is calcium ascorbate neutralized in ascorbic acid?
Due to the low pH of ascorbic acid, calcium ascorbate (neutralized vitamin C) was developed to reduce the epigastric adverse effect. Register to BYJU’S to learn more about the properties, applications, and structure of C 6 H 8 O 6 from the expert teachers.
What are the industrial uses of ascorbic acid?
Industrial/Manufacturing Uses. Ascorbic acid is used in a range of industrial and manufacturing applications, including as a developing agent and preservative in photo production, and in water purification, where it is used to help remove the taste of iodine in sterilized, potable water.
