| 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 standard. |
| Assay (Anhydrous basis): | 99.5%-100.5% |
| Residue on ignition: | Not more than 0.1% |
| Sulphate (SO4): | 0.015% max |
| Limit of oxalic acid: | 0.036% max |
| Clarity of solution: | The sample solution should show the same clarity as that of water or its opalescence should not be more pronounce than standard suspension. |
| Colour of solution: | The sample solution should not more intensely colored than standard solutions |
| Readily carbonizable substances: | The color of the acid should not be darker than that matching fluid. |
| Water: | Not more than 1.0% |
