In powder form, ascorbic acid is re

In powder form, ascorbic acid is relatively stable in air. In the absence of oxygen and other oxidizing agents it is also heat stable. Ascorbic acid is unstable in solution, especially alkaline solution, readily undergoing oxidation on exposure to the air.(2,3) The oxidation processis accelerated by light and heat and discatalyzed by trace sofcopperandiron.Ascorbic acid solutions exhibit maximum stability at about pH 5.4. Solutions may be sterilized by filtration. The bulk material should be stored in a well-closed nonmetallic container, protected from light, in a cool, dry place

Dalam bentuk bubuk, asam askorbat relatif stabil di udara. Dalam ketiadaan oksigen dan oksidator lain hal ini juga panas stabil. Asam askorbat tidak stabil dalam larutan, terutama alkali solusi, mudah mengalami oksidasi pada paparan udara. (2,3) processis oksidasi dipercepat oleh cahaya dan panas dan discatalyzed oleh jejak sofcopperandiron. Asam askorbat solusi menunjukkan stabilitas maksimum di tentang pH 5.4. Solusi dapat disterilisasi oleh filtrasi. Bahan massal harus disimpan dalam wadah elektornik baik tertutup, dilindungi dari cahaya, di tempat yang dingin, kering
