CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Pale greenish-yellow to yellowish-grey powder or granules, which may have a faint odour of burnt sugar |
|---|---|
| Color/Form | The color of /ferrous gluconate/ solution depends on pH; they are light yellow at pH 2, brown at pH 4.5, and green at pH 7. The iron rapidly oxidizes at higher pH. |
| Melting Point | The melting point for D-gluconic acid, ferrous salt dihydrate (98%) is 188 °C, decomposes. The specific optical rotation is +6.7 deg at 25 °C (c=1, H2O). /Dihydrate/ |
| Solubility | Soluble with slight heating in water. Practically insoluble in ethanol |
| Stability/Shelf Life | Aqueous solutions are stabilized by the addition of glucose. |
| Decomposition | When heated to decomposition it emits acrid smoke and irritating fumes |
| pH | Between 4 and 5,5 (10 % solution) |
| Other Experimental Properties | Ascorbic acid and aminoacetic acid cause dark coloration; with pyridoxine, green color produced. |
