In the presence of sulphuric acid (H2SO4), KI produces HI
Since is an oxidizing agent, it oxidizes HI (produced in the reaction to I2).
As a result, the reaction between alcohol and HI to produce alkyl iodide cannot occur. Therefore, sulphuric acid is not used during the reaction of alcohols with KI. Instead, a non-oxidizing acid such as H3PO4 is used.

What conditions are needed to make esters?
They vary - but nearly always involve reflux followed by removal of water often with the aid of an azeotropic solvent. An acid catalyst such as concentrated sulfuric acid is often employed but titanates and other catalysts have also been used.
In the reaction between magnesium and sulphuric acid name a metal?
Magnesium is the metal. Sulfuric acid is a compound.
What is the reaction between sulfuric acid and iron filings called?
chemical reaction.
Why is concentrated sulfuric acid employed in this reaction What is the electrophile that is produced by the reaction of sulfuric acid and nitric acid?
Concentrated sulfuric acid is employed in this reaction because it acts as a strong dehydrating agent, facilitating the generation of the electrophile needed for nitration. When sulfuric acid reacts with nitric acid, it produces the nitronium ion ((NO_2^+)), which is the active electrophile that can then react with aromatic compounds in electrophilic aromatic substitution reactions. This reaction is crucial in synthesizing nitroaromatic compounds, which are important intermediates in various chemical processes.
What are the products of an ester and water?
The products of a reaction between an ester and water are an alcohol and a carboxylic acid. This reaction is known as hydrolysis and involves the breaking of the ester bond, which results in the formation of the alcohol and carboxylic acid molecules.
What is ethanoic acid plus sulfuric acid a test for?
When a carboxylic acid is added to an alcohol, it forms an ester: Eg: CH3COOH + CH3OH -> CH3COOCH3 Sulphuric acid acts as a catalyst to this reaction Therefore if you add ethanoic acid and sulfuric acid to a unknown substance and it reacts the original substance was an alcohol.
What is the reaction between mercuric sulfate and sulfuric acid?
The reaction between mercuric sulfate and sulfuric acid forms mercuric hydrogen sulfate and sulfuric acid.
What is the reaction between ammonia and sulfuric acid?
The reaction between ammonia (NH3) and sulfuric acid (H2SO4) produces ammonium sulfate [(NH4)2SO4]. This reaction is an acid-base neutralization reaction where ammonia acts as a base and sulfuric acid as an acid, resulting in the formation of a salt.
What kind of reaction is H2SO4 SO3 plus H2O?
The reaction between sulfuric acid (H2SO4) and sulfur trioxide (SO3) to form sulfuric acid (H2SO4) is a reversible reaction known as the sulfuric acid hydration reaction. The water (H2O) acts as a reactant in this reaction to hydrate the sulfur trioxide, forming additional sulfuric acid.
What is the word equation for the reaction of sulfuric acid and sodium hydroxide?
The word equation for the reaction of sulfuric acid and sodium hydroxide is: sulfuric acid + sodium hydroxide → sodium sulfate + water.
What conditions are needed to make esters?
They vary - but nearly always involve reflux followed by removal of water often with the aid of an azeotropic solvent. An acid catalyst such as concentrated sulfuric acid is often employed but titanates and other catalysts have also been used.
The yield of ester formed in the reaction between ethanoic acid and ethanol is considerably increased if concentrated sulfuric acid is added to the reactions Suggest a reason for this?
The concentrated sulfuric acid functions as a catalyst in the esterification reaction between ethanoic acid and ethanol. It helps to protonate the carbonyl oxygen of the ethanoic acid, making it more electrophilic and reactive towards the alcohol. This results in an increased rate of ester formation and higher yield.
Why do you use sulfuric acid in the preparation of banana oil experiment?
Sulfuric acid is used in the preparation of banana oil because it acts as a catalyst to promote the esterification reaction between isoamyl alcohol and acetic acid to produce isoamyl acetate, which is the compound responsible for the banana-like scent. The sulfuric acid helps increase the rate of the reaction and improve the yield of the desired product.
What is the reaction called when sulfuric acid turns black and what is the reaction called?
Sugar Dehydration occurs when sugar is added to sulfuric acid, in the reaction the sugar is broken down into graphite which is black and bubbles with the escaping vapor. This reaction is a exothermic reaction.
What role does sulfuric acid play in the Fischer esterification process?
Sulfuric acid acts as a catalyst in the Fischer esterification process, facilitating the reaction between a carboxylic acid and an alcohol to form an ester. It helps in protonating the carbonyl group of the carboxylic acid, making it more reactive towards the alcohol, leading to the formation of the ester.
What type of reaction is formed when iron reacts sulfuric acid?
The reaction between iron and sulfuric acid is a redox reaction. Iron (Fe) reacts with sulfuric acid (H2SO4) to form iron(II) sulfate (FeSO4), releasing hydrogen gas (H2). This reaction is an example of metal-acid reaction where the metal displaces hydrogen from the acid.
What is the reaction between sulfuric acid and hydrogen peroxide?
The reaction between sulfuric acid and hydrogen peroxide produces oxygen gas and water.
