Why H2SO4 is used in oxidation of alcohol?

It protonates the chromic acid to form an oxonium ion, increasing positive charge at the chromium center. Using H+ typically protonates the electrophile, making it more electrophilic (more electron deficient = more electrophilic), just like with acid-catalyzed esterification.

Why do we use sulfuric acid in the reaction?

Reaction of sulfuric acid and H₂O When conducting chemical experiments, one must always add sulfuric acid to water, not the other way around. Sulfuric acid is a strong dehydrating substance, and concentrated sulfuric acid forces water out of various compounds. It is often used as a drying agent.

What does K2Cr2O7 do to an alcohol?

Description: Primary and secondary alcohols are oxidized by K2Cr2O7 to carboxylic acids and ketones respectively. The oxidation is physically observed by the change in color upon reduction of Cr6+ (yellow) to Cr3+ (blue).

What does Sulphuric acid react with?

Sulfuric acid reacts violently with alcohol and water to release heat. It reacts with most metals, particularly when diluted with water, to form flammable hydrogen gas, which may create an explosion hazard.

Why is sulfuric acid used instead of hydrochloric acid?

Sulfuric acid is used almost universally for neutralization reactions. It is easier and safer to use than HCl or HNO3 and is more potent than all of the other acids except for phosphoric. Although adverse reactions are always a possibility, they are rare.

Why is sulphuric acid viscous?

Sulphuric acid is highly viscous in nature because its molecules are associated with hydrogen bonding. It is a highly corrosive chemical. It is also used as a sulphonating agent in organic reactions.

When acetic acid reacts with Ethylalcohol then catalyst used in anhydrous ___?

Concentrated H2SO4 is considered to be used as an acid catalyst in esterification reactions.
