Measured properties
- Appearance
- Pale greenish-yellow to yellowish-grey powder or granules, which may have a faint odour of burnt sugar · 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 · Soluble in glycerin
- Stability
- Aqueous solutions are stabilized by the addition of glucose. · Affected by light & ferrous ion slowly oxidizes on exposure to air.
- pH
- Between 4 and 5,5 (10 % solution)
- Water solubility
- 118000 ㎎/ℓ
- n-Octanol/water partition coefficient (Kow)
- ≤ (log Pow, 25℃)
- Decomposition temperature
- ≥ 120
