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.
chemical reaction.
The chemical reaction is:Pb + H2SO4 = PbSO4 + H2
The chemical equation is:CH3COOH + C2H5OH ↔ CH3COOCH2CH3 + H2OConcentrated sulfuric acid act as a catalyst.
The acid that reacts with lithium hydroxide in a neutralization reaction to form lithium sulfate and water is sulfuric acid (H2SO4).
Magnesium is the metal. Sulfuric acid is a compound.
they do mix but there is no reaction unless a catalist like sulfuric acid were used
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.
Yes,they can undergo a neutralization reaction, the reaction between sulfuric acid and ammonia is feasible.
I think it's because sulfate is the salt of sulfuric acid. They both have the same ions, therefore have no reaction. Its like adding sulfuric acid to sulfuric acid.
chromic acid
It depends on the relative concentrations of the acid and the alcohol, and the temperature at which they are reacted.Typically, the direct reduction of an alcohol by an acid produces an ester. In this specific reaction the expected product would be propyl hydrogen sulfate, aka sulfuric acid propyl ester. Esters and their "mother alcohol", in turn, react to form ethers, in this case dipropyl ether, with the acid and water as a byproduct.This esterification reaction is readily reversible; the ether will crack water to reform the alcohol, and the ester will hydrolyze in the water to reform the acid and alcohol. By Le Chatelier's principle, these reactions will form an equilibrium between the acid, alcohol, ester and ether. The ether can be recovered by gentle heating to distill it, which shifts the equilibrium leading to sustainable production of the ether. The reaction can be quenched with water, which will hydrolize the ester back into the alcohol and acid, or by adding a strong base to neutralize the acid (in either case the ester is consumed by this process).At very high concentrations of sulfuric acid (that would be called "fuming sulfuric acid" or oleum), the acid will dehydrate the alcohol (removing its hydroxyl and an additional hydrogen, forming a water molecule to balance the water and sulfate ions) to form an alkene, in this case propylene. This is again a reversible reaction; adding water to the mixture will lower the concentration of sulfuric acid and cause acid-catalyzed hydration of the propylene to reform propanol.
the sulfuric acid acts a catalysts and speeds up the reaction while absorbing the excess of water so it makes it more pure
It denatures it
yes.
Cool it down, or lower the concentration of zinc and the sulfuric acid.
There are several metals which do not react with sulfuric acid; once such metal is gold.
H2SO4 + 2H2O ---> 2H3O- + SO4-2 Sulfuric acid + water ---> hydronium + sulfate
