To neutralize the HCl formed during polymerisation.
1,6 diaminohexane + diacid chloride -> nylon 6,10 + HCl
2 HCl + Na2CO3 -> 2 NaCl + H2O + CO2
It would be disadvantageous to leave out the Na2CO3 because the chloride acid produced in the reaction would cause for a lower yield. By adding the sodium carbonate the reaction is driven more toward the products resulting in a higher yield. The use of inorganic bases would also increase the strength of the polymer "rope."
a great paper on this is "The Nylon Rope Trick" by Paul Morgan and Stephanie Kwolek http://www.usm.edu/pattonresearchgroup/PSC341/jce.pdf

What does 1M solution of sodium carbonate mean?
A 1M solution of sodium carbonate means that it contains 1 mole of sodium carbonate dissolved in 1 liter of solvent (usually water). This concentration is used in chemistry to describe the amount of the solute (sodium carbonate) present in the solution.
Sodium carbon oxygen?
Sodium carbonate is a white, odorless solid compound commonly known as soda ash or washing soda. It is used in glassmaking, water softening, and as a cleaning agent. The chemical formula for sodium carbonate is Na2CO3.
Would you need to use sodium carbonate for the diazotization of p-nitroaniline?
No, You would need a weak acid so the solution would be acidic
Would you need to use sodium carbonate for the diazotization of m-nitroaniline?
You need to use sodium carbonate when you are attempting to diazotize a poorly soluble acid, such as sulfanilic acid. m-nitroaniline isn't acidic, so adding sodium carbonate would have no effect.
Why is sodium hydrogen carbonate used as a treatment for ant stings?
Sodium hydrogen carbonate, or baking soda, can help neutralize the venom from ant stings, reducing pain and inflammation. Its alkaline nature can help counteract the acidic venom injected by ants, providing relief from the sting.
What ammonia used for?
we use it for many purposes. Mainly we make sodium carbonate.
Is sodium carbonate the same as sodium bicarbonate?
No, sodium carbonate (Na2CO3) and sodium bicarbonate (NaHCO3) are two different compounds. Sodium carbonate is commonly known as washing soda and is used in cleaning products, while sodium bicarbonate is known as baking soda and is often used in baking and as an antacid.
Is sodium bicarbonate the same as sodium carbonate?
No, sodium bicarbonate (baking soda) and sodium carbonate (soda ash) are different compounds with distinct chemical compositions. Sodium bicarbonate is commonly used in baking and as an antacid, while sodium carbonate is used in making glass, detergents, and other industrial processes.
What is the use of sodium carbonate in agriculture?
Sodium carbonate can be used in agriculture as a pH regulator to adjust the acidity of soil. It can also be used as a source of carbon for photosynthesis in plants. Additionally, sodium carbonate can help in controlling pests and diseases in crops by acting as a fungicide.
Cement sand limestone and sodium carbonate make what?
Cement, sand, limestone, and sodium carbonate combined can form a type of mortar or cement mixture that can be used in construction. Sodium carbonate helps improve the workability of the mixture and can act as a stabilizer for the cement.
Is sodium carbonate compound?
Yes, sodium carbonate is a compound. It is a white, odorless powder that is commonly used in household products such as cleaning agents and water softeners. Sodium carbonate is composed of sodium ions and carbonate ions in a specific ratio, giving it its chemical properties and characteristics.
What does citric acid and sodium carbonate make?
Citric acid and sodium carbonate react to form carbon dioxide gas, water, and sodium citrate. This reaction is commonly used in effervescent tablets to produce fizz when dissolved in water.
What does citric acid sodium carbonate make?
Citric acid and sodium carbonate combine to form sodium citrate, water, and carbon dioxide, in a chemical reaction. This reaction is commonly used in effervescent products such as bath bombs or antacids.
What is Na2CO3.10H2O?
Sodium carbonate decahydrate, also known as washing soda, is a hydrate form of sodium carbonate with 10 molecules of water incorporated into its crystal structure. It is commonly used in household cleaning products and as a water softener.
What does 1M solution of sodium carbonate mean?
A 1M solution of sodium carbonate means that it contains 1 mole of sodium carbonate dissolved in 1 liter of solvent (usually water). This concentration is used in chemistry to describe the amount of the solute (sodium carbonate) present in the solution.
Is ball mill used as a raw material for the commercial preparation of soda ash sodium carbonate?
A ball mill is a machine used for grinding chemicals, not a raw material. It's not used in the manufacture of sodium carbonate because the process they use to make sodium carbonate kicks it out as a usable powder. In the US, we don't use the synthetic way because we have a LOT of a mineral called trona in Wyoming - so much that it supplies a quarter of the world's sodium carbonate requirements. That is turned into sodium carbonate by digging it out of the ground, grinding it in a rock crusher, dissolving the sodium carbonate into water, then filtering the solution and evaporating it...once again, producing a usable powder.
What is Sodium carbonate made up of?
Sodium carbonate is an ionic compound with the formula Na2CO3. It is composed of sodium ions ( Na+) and carbonate ions (CO32-). The carbonate ion is in turn composed of carbon and oxygen.
