Why is it necessary to wash the crude cyclohexene product with aqueous sodium carbonate?
Washing the crude cyclohexene product with aqueous sodium carbonate helps to remove any acidic impurities present in the mixture. This process neutralizes any residual acid that may be present from the reaction, resulting in a purer product. Additionally, washing with aqueous sodium carbonate can help remove water-soluble impurities, improving the overall quality of the final product.
How does the reaction between carbon dioxide and aqueous sodium hydroxide affect the pH of the solution?
When carbon dioxide reacts with aqueous sodium hydroxide, it forms sodium carbonate and water. This reaction increases the pH of the solution because sodium carbonate is a weak base.
Are Dilute sulfuric acid and aqueous sodium carbonate produced water and salt only?
When dilute sulfuric acid reacts with aqueous sodium carbonate, the products formed are water, salt (sodium sulfate), and carbon dioxide gas. This reaction is a type of double displacement reaction where the ions in the reactants switch partners to form the products.
Is sodium carbonate soluble in aqueous solution?
Yes, sodium carbonate (Na2CO3) is soluble in water. When dissolved in water, it dissociates into sodium ions (Na+) and carbonate ions (CO3^2-).
What is colour of an aqueous solution of sodium carbonate in presence of a drop of phenolphthalein?
The color of an aqueous solution of sodium carbonate in the presence of phenolphthalein would be pink. Phenolphthalein turns pink in basic solutions with a pH above 8.2. Sodium carbonate is a basic compound that will cause the phenolphthalein indicator to change color to pink.

Why was it necessary to wash the cyclohexene product with aqueous sodium carbonate?
Washing the cyclohexene product with aqueous sodium carbonate helps to remove any acidic impurities that may be present. The sodium carbonate solution neutralizes any residual acids, ensuring a purer product. Additionally, it can also help remove any water-soluble impurities that may be present in the product.
Why is sodium carbonate added during extractionin preparation of cyclohexene?
if cyclohexene is prepared by dehydration of cyclohexanol in the presence of a strong acide like H3PO4, sodium carbonate will be used to neutralize the acidic medium
Is sodium carbonate an aqueous or a solid?
its aqueous when dissolved in water and solid (@STP) when not
What is the balanced chemical equation for the reaction of aqueous calcium chloride with aqueous sodium carbonate to produce calcium carbonate precipitate in an aqueous sodium chloride solution?
The chemical reaction isȘCaCl2 + Na2CO3 = CaCO3 + 2 NaCl
What do you get when aqueous solutions of sodium carbonate and zinc chloride are combined?
When aqueous solutions of sodium carbonate and zinc chloride are combined, a double displacement reaction occurs. This results in the formation of zinc carbonate, which is a white solid precipitate that settles out of the solution, and sodium chloride, which remains dissolved in the solution.
How does the reaction between carbon dioxide and aqueous sodium hydroxide affect the pH of the solution?
When carbon dioxide reacts with aqueous sodium hydroxide, it forms sodium carbonate and water. This reaction increases the pH of the solution because sodium carbonate is a weak base.
Sodium carbonate into a chemical equation?
Sodium Carbonate is the disodium salt of the carbonate anion. Sodium is a +1 cation while carbonate is a -2 anion. It is a basic salt when dissolved in water. Sodium carbonate doesn't have a equation itself, but when dissolved in water (deionization), it looks like this: Na2CO3(s) <------> 2 Na+(aq) + (CO3)2-(aq) In words: solid sodium carbonate is in equilibrium with two aqueous sodium ions of +1 charge and one aqueous carbonate ion of -2 charge. Carbonate is one carbon, 3 oxygens.

Is CO3 aqueous?
No, CO3 is not typically found in the aqueous state. It is more commonly found in solid form as the carbonate ion, typically as compounds like calcium carbonate (CaCO3) or sodium carbonate (Na2CO3). In aqueous solutions, these compounds dissociate into their respective ions.
