Molecular Formula:C6H7NaO6
Formula Weight:198.11
Specification:100g
Description:
Sodium ascorbate is a more bioavailable form of vitamin C that is an alternative to taking ascorbic acid as a supplement. The molecular formula of this chemical compound is C6H7NaO6. As the sodium salt of ascorbic acid (vitamin C), it is known as a mineral ascorbate.
Sodium ascorbate normally provides 131 mg of sodium per 1,000 mg of ascorbic acid (1,000 mg of sodium ascorbate contains 889 mg of ascorbic acid and 111 mg of sodium).
As a food additive, it has the E number E301 and is used as an antioxidant and an acidity regulator.
Sodium corbate added 10ml of water to dissolve, the solution should clear colorless; Such as turbidity, and turbidity standard solution 1 (2 2010 edition pharmacopoeia appendix Ⅸ B) comparison, not more; For color development, filter through no. 4 vertical melting glass funnel, take the filtrate, and measure the absorbance at the wavelength of 420nm by uv-visible spectrophotometry, no more than 0.06.
Sodium ascorbate0.25g, add 5.0ml water, shake to dissolve, add 1ml dilute acetic acid and 0.5ml calcium chloride solution, shake well, and leave for 1 hour as the sample solution; Precision weigh 75mg oxalic acid, put it into a 500ml measuring bottle, add water to dissolve and dilute it to the scale, shake it well, take 5ml, add 1ml dilute acetic acid and 0.5ml calcium chloride test solution, shake it well, and leave it for 1 hour as the control solution. The turbidity produced by the test solution should not be thicker than that of the control solution (0.3%).
