What is the purpose of adding sodium acetate to the reaction mixture in preparation of acetanilide?
In the synthesis of acetanilide the hydrochloride salt of aniline is used in order to increase the solubility in water. The sodium acetate acts as a base and reacts with the HCl to produce acetic acid. Once the acetanilide product is no longer a hydrochloride salt, its solubility in water is decreased and it crystalises out. The main byproducts are sodium chloride and acetic acid which remain soluble in the water and are removed when the crude product is filtered off.

Why you use ice in the hydrolysis of ethyl acetate?
Ice is used in the hydrolysis of ethyl acetate to help regulate the temperature of the reaction. The hydrolysis reaction is exothermic, meaning it produces heat. By adding ice, the temperature can be controlled to prevent the reaction from getting too hot and potentially boiling over or causing side reactions.
Does sodium acetate form a homogeneous mixture in water?
white crystals are formed quickly when mixed and its an exothermic reaction meaning it gives off heat its what is used on hand warmers there is a video on youtube. the water is the acid and the sodium acetate is the base and takes a hydrogen from the water forming hydroxide ions and acetic acid. here is the reaction. C2H3O2-(aq) + H2O(l) HC2H3O2(aq) + OH-(aq)
Why you add sodium carbonate to the mixture during preparation of ester?
Sodium carbonate is added during the preparation of esters to neutralize the acidic byproduct formed during the reaction. This helps to facilitate the esterification reaction and improve the yield of the desired ester product.
You sodium acetate a element a compound or a mixture?
Sodium acetate, NaOOCCH3 is a chemical compound, a salt of acetic acid
How do you extract isoamyl acetate from banana?
One common method to extract isoamyl acetate from banana is by steam distillation. The banana is mashed and mixed with water, then heated under reflux to release the isoamyl acetate. The mixture is distilled to separate the volatile isoamyl acetate from other components.
Why sodium sulphate is added in preparation of para bromo acetanilide?
Sodium sulfate is added in the preparation of para bromoacetanilide to facilitate the separation of the product from the reaction mixture. It helps in forming a complex with excess bromine and bromine water, allowing easy removal of impurities. Sodium sulfate is also used to dry the organic layer during the extraction process.
Why is a large excess of acetic acid used in the preparation of isopentyl acetate?
Esterification of an acetic acid with isopentyl alcohol can can be used to prepare isopentyl acetate because the equilibria would not favor the formation of the ester, so equilibira will shift to the right IF we use excess amount of one of the reagents (acetic acid). We used large amounts of acetic acid because it's less expensive and it's easier to remove from a reaction mixture than isopropyl alcohol.
How can ethyl acetate be made?
Ethyl acetate can be made through a process called esterification, where ethanol and acetic acid react in the presence of a catalyst, typically sulfuric acid. This reaction forms ethyl acetate and water as byproducts. The mixture is then distilled to separate and purify the ethyl acetate.
Why acetanilide brominates in the ortho and para positions and the amount of o-bromoacetanilide?
Acetanilide undergoes bromination in the ortho and para positions due to the presence of the activating amino group that directs the electrophilic bromine to these positions. In the reaction mixture, the para-bromoacetanilide is the major product compared to the ortho isomer, typically in a ratio of about 4:1.
Reaction between soda lime and sodium acetate?
When soda lime (a mixture of calcium hydroxide and sodium hydroxide) comes in contact with sodium acetate, a base-acid reaction will occur. The sodium acetate will react with the hydroxide ions from the soda lime to form sodium hydroxide and acetic acid. This reaction will result in the neutralization of sodium acetate and the formation of sodium hydroxide and acetic acid as the products.
Is sodium acetate a mixture compound or element?
Sodium acetate is a chemical compound.

Ice is used in the hydrolysis of ethyl acetate to help regulate the temperature of the reaction. The hydrolysis reaction is exothermic, meaning it produces heat. By adding ice, the temperature can be controlled to prevent the reaction from getting too hot and potentially boiling over or causing side reactions.
What happens before during and after reflux while preparing ester of isoamyl acetate?
Before refluxing, reagents such as isoamyl alcohol and acetic acid are mixed in a reaction flask. During reflux, the reaction mixture is heated under reflux conditions to allow the esterification reaction to occur. After reflux, the reaction mixture is cooled and the ester product, isoamyl acetate, is isolated using techniques such as extraction or distillation.
Is energy absorbed during preparation of a mixture?
Depends on the mixture. There are two different reactions when atoms bond: exothermic and endothermic. During an exothermic reaction, energy is given off in the form of heat or light. In a endothermic reaction, energy is absorbed.
How do you prepare nickel acetate?
To prepare nickel acetate, you can mix nickel oxide or nickel carbonate with acetic acid in the presence of water. The reaction typically involves heating the mixture to promote the formation of nickel acetate. Once the reaction is complete, the resulting solution can be further processed and purified to obtain the desired nickel acetate product.

How do you separate mixture of methanol and ethyl acetate?
You can separate a mixture of methanol and ethyl acetate by using fractional distillation. Since they have different boiling points (methanol: 64.7°C, ethyl acetate: 77.1°C), you can heat the mixture to a temperature between the two boiling points to selectively vaporize and collect each component.
