|---|---|
| Description: | Colourless crystals or a white powder; slightly hygroscopic in moist air. |
| Solubility: | Very soluble in water, freely soluble in ethanol (95%), sparingly soluble in ether. |
| Identification A (By IR): | IR spectra of the sample should be concomitant with IR spectra of the corresponding standard |
| Identification B (By Chemical test): | It gives reaction (A) of citrates. |
| Identification C (By Chemical test): | A 10.0% w/v solution is strongly acidic. |
