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.
Perchloric acid (HClO4) is the strongest of ALL (5 kinds of) chloric acids, hence it has the lowest (even the most negative) pKa value.
However there is no difference between the pKa values of HClO4 and HClO4 (?!). They are (not coincidentially) equal.
Chlorine (Cl) is more electronegative than selenium (Se) and so exerts a stronger "pull" on the electrons in a molecule. This makes it easier for a hydrogen ion (H+) to break off.
Both are strong acids in water, it means: stronger than H3O+,
but HClO4 is much stronger than HClO3.
HClO4 is a stronger acid than HClO3 because its ka value is larger
Oxygen is electron withdrawing, meaning it pulls electrons away from the rest of the molecule. More oxygen atoms, then make it easier for an H+ ion to break off.
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).
This compound, HCLO4, is perchloric 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.
Chlorine (Cl) is much more electronegative than silicon (Si). This means that chlorine exerts a much stronger "pull" on the electrons in a perchloric acid molecule than silicon does in a silicic acid molecule. The stronger pull makes it easier for a hydrogen ion (H+) to break away. The greater the degree of dissociation the stronger the acid. Perchloric acid dissociates completely in water, thus marking it as a strong acid. Silicic acid only dissociates partially, thus marking as a weak acid.
HSO4- is a stronger acid than NH4+

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)

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.
HSO4- is a stronger acid than NH4+
chlorine is high electronegative then bromine so it attracts the shared electrons powerfully so ' O-H ' bond in HOCl is weaker as compare to HOBr, therefore HOCl easily donate the H+ ion in water and it is stronger acid than HOBr.
A strong acid dissociates more completely than a weak acid.
A strong acid dissociates more fully than a weak
No, the conjugate acid of most strong bases is water.
0.1 M strong acid is a better conductor than 1 M weak acid
