Which acid is stronger h2so4 or h2so3?
(a) H2SO4 is stronger than H2SO3 because it has more O atoms, and H2SO3 is stronger than H2CO3 because it has a more electronegative central atom (ENS > ENC), so H2SO4 is stronger than H2CO3..
Is HClO4 a strong acid?
The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only). … Remember what we mean by a weak acid or weak base. They simply do not ionize completely whereas a strong acid or base does.
Is H3AsO4 a weak acid?
H3AsO4 (arsenic acid) is a much stronger acid than H3AsO3 (arsenous acid). … 2.2 is a moderately strong acid. 9.2 is very weak acid.
Which acid is stronger h3po4 or H3AsO4?
Step 1 : Rule : For oxoacids with different numbers of O atoms, acid strength increases with number of O atoms (or O.N. of central nonmetal). The electronegative O atoms pull electron density away from E, which makes the O—H bond more polar. … H3PO4 is a stronger acid than H3AsO4.
Which is the most dangerous acid?
Incidents involving hydrogen fluoride, or hydrofluoric acid, are not common, but the consequences of exposure to this compound by any means can be devastating. This little-known acid has unique properties that make it extremely dangerous to emergency personnel and others.
What is the most corrosive liquid?
Sodium hydroxide (also known as lye) is one of the most corrosive of all bases. It generates significant heat when diluted and has an extremely high alkalinity (concentration of alkali elements in the solution).
Is hso4 a weak acid?
HSO4- is not a strong acid because it is actually a weak acid. That means that it partially dissociates to make H+ and SO4^2-. However, H2SO4 is a strong acid and completely dissociates to create H+ and HSO4-.
Which is more stronger HCl or h2so4?
HCl is a stronger acid than H2SO4 because a proton more easily separates from chloride ion than from hydrogen sulphate ion and this is reflected in their dissociation constants.
Is H2SeO4 stronger than h2so4?
Between similar oxyacids of elements of the same group, the greater the electronegativity of the element, the stronger will be the acid formed by it. Hence H2SO4 should be stronger than H2SeO4.
Is h2co3 a strong acid?
No, H2CO3 is not a strong acid. Strong acid are those which completely get ionised in water forming H+ ions whereas weak acid are those which partially get ionised. So carbonic acid (H2CO3) is a weak acid.
What is the strongest base in the world?
The methyl anion H3C– was the strongest known base for 30 years, until Tian and colleagues made the lithium monoxide anion in 2008, which has held the record since. Now, scientists in Australia have knocked LiO– down to second place, making a gas-phase dianion with the highest basicity ever found.
Is h2so4 strong or weak?
Examples of strong acids are hydrochloric acid (HCl), perchloric acid (HClO4), nitric acid (HNO3) and sulfuric acid (H2SO4). A weak acid is only partially dissociated, with both the undissociated acid and its dissociation products being present, in solution, in equilibrium with each other.
Which is the strongest acid?
carborane acidThe world’s strongest acid, at least a million times more potent than concentrated sulphuric acid, has been made in a lab in California. Perhaps confusingly, it is also one of the least corrosive. The compound, called a carborane acid, is the first ‘superacid’ that can be stored in a bottle, say its creators.
Which is the weakest acid?
hydrofluoric acidThe only weak acid formed by the reaction between hydrogen and a halogen is hydrofluoric acid (HF).
Is h3po4 a strong acid?
Weak acids are only slightly ionized. Phosphoric acid is stronger than acetic acid and so is ionized to a greater extent. Acetic acid is stronger than carbonic acid, and so on….Strong and Weak Acids and Acid Ionization Constant.AcidConjugate BaseWeak AcidsH3PO4 (phosphoric acid)H2PO4− (dihydrogen phosphate ion)CH3COOH (acetic acid)CH3COO− (acetate ion)6 more rows•Jun 26, 2013
