monosodium phosphate anhydrous - Physico-chemical Properties
| Molecular Formula | H2NaO4P |
| Molar Mass | 119.977011 |
| Physical and Chemical Properties | White crystalline powder. Melting point 190 ℃. Easily soluble in water, its aqueous solution is acidic. When heated to 225~250 ℃, it will be dissolved into sodium acid pyrophosphate, and when heated to 350~400 ℃, it will be dissolved into sodium metaphosphate. When monohydrate and dihydrate are heated to 100 ℃ and 95 ℃, they lose crystal water and become anhydrous sodium dihydrogen phosphate respectively. Slightly hygroscopic. |
monosodium phosphate anhydrous - Introduction
Anhydrous monosodium phosphate, chemical formula NaH2PO4, is an anhydrous substance. The following is an introduction to the nature, use, preparation and safety information of anhydrous monosodium phosphate:
Nature:
1. Appearance: colorless crystal or white crystalline powder.
2. density: 2.04g/cm³.
3. melting point: 190 ℃.
4. Solubility: Soluble in water, acidic solution.
Use:
1. as a food additive: anhydrous monosodium phosphate can be used as a buffer, nutritional supplement and enzyme activator in food.
2. as a fertilizer additive: anhydrous monosodium phosphate is commonly used in the preparation of phosphate fertilizer and the control of soil pH.
3. For water treatment: It can be used as a water treatment agent to control the pH value and hardness of the water.
Preparation Method:
The preparation of anhydrous sodium phosphate can be obtained by the reaction of phosphoric acid and sodium hydroxide:
H3PO4 NaOH → NaH2PO4 H2O
Safety Information:
1. avoid contact with oxidants, avoid contact with skin and eyes.
2. use should pay attention to protective measures, such as wearing protective glasses and chemical gloves.
3. in the process of operation, pay attention to ventilation, avoid inhalation of dust.
4. in case of accidental ingestion or contact, please seek medical treatment or professional help immediately, and bring the product label for diagnosis and treatment.
Anhydrous monosodium phosphate is relatively safe under proper conditions of use and storage, but should be used with care to ensure personal safety.
