Description | Colorless crystals or white, crystalline powder. |
Solubility | Freely soluble in water and very soluble in boiling water. Insoluble in alcohol. |
Identification | A) solution (1 in 20) responds to the test for Sodium and for citrate. Sodium: A dense precipitate is formed. Citrate: A light red colour is produced. |
Alkalinity | No pink colour is produced by 1 drop of phenolphthalein TS. |
Water | Between 10.0% and 13.0%. Dry it at 180°C for 18 hours. |
Alkalinity | Not more than 0.2 ml of 0.1M hydrochloric acid or 0.1M sodium Hydroxide is required to change the colour of the indicator. |
Tartrate | No crystalline precipitate is formed. |
Heavy Metals | Not more than 0.001%. |
Assay | 99.0 % to 100.5 % (On Anhydrous Basis) |

Identification B. Sodium | 1. A dense, white precipitate is formed. |
Appearance of Solution | Solution S is clear and colourless. |
Acidity or Alkalinity | Not more than 0.2 ml of 0.1M hydrochloric acid or 0.1M sodium Hydroxide is required to change the colour of the indicator. |
