Is H2SO3 or H2SO4 stronger?

H2SO4 is a stronger acid than H2SO3 .

Is H2SO4 weaker than H2SO3?

Which is stronger H2CO3 or H2SO4?

Re: H2SO4 vs H2CO3 Because HSO4- has sulfur, which has a greater electronegativity than carbon, the anion is more stable (Due to electron delocalization) and thus its acid is stronger.

Is H2SO3 weak or strong?

Sulfurous acid, H2SO3, is a weak acid capable of providing two H+ ions (pKa1 = 1.9, pKa2 = 7.0).

Is H2CO3 is a strong acid?

Is carbonic acid a strong acid? No, carbonic acid is not a strong acid. H2CO3 is a weak acid that dissociates into a proton (H+ cation) and a bicarbonate ion (HCO3- anion). This compound only partly dissociates in aqueous solutions.

Why is sulfuric acid stronger than sulfurous?

Sulphuric acid is stronger than sulphurous acid since the sulphur atom in sulphuric acid has more co-ordinated oxygen atoms.

Is H2CO3 strong or weak acid?

Carbonic acid is a type of weak acid formed from the dissolving of carbon dioxide in water. The chemical formula of carbonic acid is H2CO3. Its structure consists of a carboxyl group with two hydroxyl groups connected. As a weak acid, it partially ionizes, dissociates or rather, breaks apart, in a solution.

Which is stronger hno2 or H2CO3?

HNO3 is very strong acid as compare to H2CO3 because HNO3 completely dissociate in water in order to provide H+ ion. Whereas in case of H2CO3 it doesn’t completely dissociate. In fact H2CO3 is used in manufacturing beverages and soft drink as it is so weak that we can drink is easily and has no any harmful effects.

Is H2SO4 weak or strong?

Strong acids are 100\% ionized in solution. Weak acids are only slightly ionized. Phosphoric acid is stronger than acetic acid and so is ionized to a greater extent….Strong and Weak Acids and Acid Ionization Constant.

Acid	Conjugate Base
HCl (hydrochloric acid) (strongest)	Cl− (chloride ion) (weakest)
H2SO4 (sulfuric acid)	HSO4− (hydrogen sulfate ion)

Is H2CO3 strong or weak?

H2CO3 is a weak acid that dissociates into a proton (H+ cation) and a bicarbonate ion (HCO3- anion).

Is H2CO3 stronger acid than HCO3?

H2CO3 is a weak acid and does not completely dissociate. The product, HCO3-, is not stable and can react again with water to contribute to the pH. HCO3- will act as a base by plucking off the proton from H2O, and forming a basic solution.
