| Description: | Colourless, translucent crystals or white granular to fine crystalline powder. Efflorescent in dry air.(Note: The product may cause lumps or hardening over the storage). |
| Solubility: | Very soluble in water, freely soluble in alcohol, very slightly soluble in ether, |
| Identification A (By IR): | IR spectra of the sample should be concomitant with IR spectra of the corresponding standadrd |
| Assay (Anhydrous basis): | 99.5%-100.5% |

| Sulphate (SO4): | NMT 0.015% |
| Limit of oxalic acid: | NMT 0.036% |
| Clarity of solution: | The sample solution shows the same clarity as that of water or its opalescence is not more pronounced than standard suspension A. |
| Colour of solution: | The sample solution is not more intensely colored than water or standard solutions A, B, and C . |
| Readily carbonizable substances: | The color of the acid is not darker than that of a similar volume of matching fluid K . |
| Water: | 7.5% to 9.0% |
