HClO4 is a stronger acid than H2SO4 because the chlorine (Cl) is more electronegative than sulfur (S). As a result the chlorine atom exerts a stronger "pull" on the electrons in a molecule than sulfur does, making it easier for a hydrogen ion (H+) to break off.

Is bromine a strong or a weak acid?

Bromine itself is not considered an acid. However, it can react with water to a small degree to form hydrobromic acid (HBr), a strong acid and hypobromous acid (HBrO) a weak acid. Br2 + H2O --> HBr + HBrO


What is the name for aqueous HCLO4?

This compound, HCLO4, is perchloric acid.


Which is strongest acid among H2SO4 and HClO4 acid?

Perchloric acid (HClO4) is a stronger acid than sulfuric acid (H2SO4) because perchloric acid has a more acidic hydrogen that is easier to release as a proton, resulting in a stronger acid.


Is a carbonic acid weak or strong?

H2CO3 is a weak acid--you can tell because there is one less H than O. Strong ternary acids have at least 2 less H than O (for instance, H2SO4, HClO3, HClO4). Strong binary acids are made of halogens, except for weak HF (so they are HCl, HBr, HI).


Is HClO4 or H3PO4 stronger?

HClO4 (perchloric acid) is stronger than H3PO4 (phosphoric acid) because it has a more acidic proton which can dissociate more readily in water, leading to a higher concentration of H+ ions in solution.


What are the 5 acids?

There are far more than 5 acids. There are, however, 6 (some sources say 8) strong acids. They are: Hydrochloric acid (HCl) Hydrobromic acid (HBr) Hydroiodic acid (HI) Perchloric acid (HClO3) Nitric acid (HNO3) Sulfuric acid (H2SO4) Some sources also list Chloric acid (HClO3) and Periodic acid (HIO4) as strong acids. There are hundreds of weak acids. Common example include: Acetic acid (CH3CO2H) Formic acid (HCO2H) Carbonic acid (H2CO3) Phosphoric acid (H3PO4) Hydrofluoric acid (HF) Hydrosulfuric acid (H2S)


Is perchloric acid a weak acid?

Actually perchloric acid (HClO4) is a much stronger acid than chlorous acid (HClO2). The strength of an acid is determined by the ability of a hydrogen ion (H+) to break away. Perchloric acid has more oxygen, which is electron withdrawing, in a molecule, making it easier for the H+ ion to break away.


Why H2SO4 is less stronger than HClO4?

That's still I have some confusion. You can never tell HCl is Stronger than H2SO4, because H2SO4 can donate two protons in reaction. So H2SO4 is seems stronger.But in another way in water HCl has more HIGHER Ka value. So in that sense we can tell:HCl is stronger.Added: The number of protons in an acid molecule doesn't tell you about its strength. Look for instance at phosphoric acid: H3PO4 even has three protons (H+) but they are all three to be considered as weak!The strength of an acid is ONLY determined by Ka (acid equilibrium constant) and called weak if Ka1. For mono-protic acids like HCl, it means that more than about 50% to 65% is protolysed (has split of protons).The pH however is SLIGHTLY determined by the number of protons (being 1 or 2) but only for strong acids: pH is at maximum 0.3 pH units lower for a strong 'double proton' acid compared with a 'single proton' acid. ( -log10 of 2 equals -0.3). With weak acids the second protolysis can mostly be neglected.


How acid is strong and weak?

A strong acid dissociates more fully than a weak


What makes a strong acid differ from a weak acid?

A strong acid dissociates more completely than a weak acid.


Is hso4 a strong or weak acid?

HSO4- is a stronger acid than NH4+


WHAT determines if an acid will be strong or weak?

The ability of dissociation and the concentration is what causes an acid to be strong or weak. If it is strong, it will dissociate in water and have a pH lower than 7. A weak acid will partially dissociate in water, and it will have a pH of 7 or greater.
