Sulfuric acid acts as a catalyst in esterification.

You can use 85% phosphoric acid, or concentrated sulfuric acid. It depends on your method, but either works.

Concentrated sulfuric acid has 98 % H2SO4.

Yes, concentrated sulfuric acid is a liquid.

No. Even concentrated hydrochloric acid contains much water. Concentrated sulfuric acid, which can be completely anhydrous, is much more effective as dehydrating agent.

The chemical reaction (a dehydration reaction) is:C12H22O11 + H2SO4 = 12 C + 11 H2O

The chemical equation is:CH3COOH + C2H5OH โ†” CH3COOCH2CH3 + H2OConcentrated sulfuric acid act as a catalyst.

Ethanol is either formed from a dehydration reaction of ethene and water catalyzed with concentrated sulfuric acid. Or as a waste product of yeast.

By diluting the concentrated sulphuric acid accordingly.

By diluting the concentrated sulphuric acid with distilled water.

the widely used catalyst is V2O5 .

is concentrated sulphuric acid toxic

Concentrated sulfuric acid has sulfuric acid molecules where dilute sulfuric acid has sulfate ions and hydrogen ions. Water in the diluted solution acts as the ionization medium.

In concentrated sulfuric acid usually about 1%

Sulfuric acid acts as a catalyst and dehydrant. It is also serves as a source of protons during the esterification of salicylic acid with acetic anhydride.

Concentrated sulfuric acid might, but dilute sulfuric acid does not corrode copper.

H2SO4 acts as a catalyst to speed up the reaction between the various alcohols and carboxylic acids in order to form esters and water as product

A substance that speeds up the reaction is a catalyst. Catalyst examples include sulfuric acid and manganese dioxide. Temperature and light are examples of a catalyst.

No, although "concentrated" sulfuric acid (essentially pure H2SO4) is less dissociated than dilute sulfuric acid, simply because there's no water around for it to dissociate in.

Sulfuric acid is better, as it catalyzes more reactions

Dissolve excess Sulfur trioxide in concentrated Sulfuric acid

1 Normal (N) is made by adding 28 ml of concentrated sulfuric acid with deionized water to a final volume of 1 Liter (L). Concentrated Sulfuric acid is 35.71 N, where 2 N = 1 M (molarity).
