Detailed Product Description

 

widely used in medicine, papermaking, metallurgy, glass, textile, dyestuff industry, etc.
food fermentative microbiology

[Nature]  An ordinary situation of white powder, for strong electrolytes.Density 2.532g/cm3, melting point 851 ° C, easily soluble in water, with salt connectivity.

[Outer view]  White powder, is solid

[Molecular formula]  Na2CO3

[Mouth taste]  acerbity

[Dissolve solution degrees   21g 20°C

[Chemical properties] 

   Easy to make decent in the air, Its peroxide solution assumes the alkalinity, Can produce certain with acid reaction.

[Firm set sex] 

Stability stronger, but high temperatures also can decompose,Generate oxidation sodium and carbon dioxide.Long-term exposure to air can absorb moisture from the air and carbon dioxide,

Generate sodium bicarbonate, and formed lumps.Hygroscopic is very strong,Very easy to form lumps, do not break down at high temperature.

[Dissolve solvings]  Soluble in water,

Slightly soluble in absolute ethyl alcohol, Insoluble in propanol.Sodium carbonate, soluble in water,Is a kind of alkali salt,Dissolves after the water has the hydrolitic reaction, Causes the solution to turn the alkalinity,

Have certain corrosive,Can carry on and the response with the acid, Produces the corresponding salt and emits the carbon dioxide.

     Wide range of uses, glass, soap, detergent, textile, leather, spices, dyes, medicines and other reagents for the analysis of important raw materials, but also for the pharmaceutical industry and the photographic plate is widely used in glass, chemicals, paper , metallurgy, medicine, textile and food industries TV special reagent for the food industry, as a neutralizer, leavening agents, such as the manufacture of amino acids, soy foods such as bread and flour, bread and so on.Still can match into buck to join in the pasta, increase elasticity and ductility. As detergent used for wool rinse, bath salt and medical use, alkali in tanning agent.Basic chemical raw materials, widely used in medicine, papermaking, metallurgy, glass, textile, dyestuff industry, etc. food fermentative microbiology.
