Which Is The Strongest Acid HClO4? - Fixanswer

Since the identity of the central atom is the same chlorine as is the number of hydrogens compare the number of oxygen atoms. The HClO4 has the

most oxygen atoms

so it would have to be the strongest acid.

Which is strongest acid HClO4 HClO3?

Thus, the order of acidic strength is HClO < HClO2 < HClO3 < HClO4 As the number of oxygen atoms attached to chlorine increases, acid strength increase. Hence, the correct option is (

2

).

Which is the stronger acid HClO4 or h3po4?

oxyacids. …it can be predicted that perchloric acid,

HClO
₄

, is a stronger acid than sulfuric acid, H
₂
SO
₄
, which should be a stronger acid than phosphoric acid, H
₃
PO
₄
. For a given nonmetal central atom, the acid strength increases as the oxidation number of the central atom increases.

Which is the strongest acid H2SO4 or HClO4?

41 These results can be interpreted based on the fact that

HClO4 is a stronger acid

and consequently a weaker Lewis base than H2SO4, and cannot easily donate its electron to an empty orbital of the B atom of BX3.

Is HClO4 a strong acid?

The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only).

Is HClO4 stronger than h2so3?

Is HClO4 stronger than h2so3? … So

obviously HClO4 is strongest and so on

. Also if two acids have same OS of central atom, count the number of oxygen atoms linked to it and again its directly proportional.

Which acid is the weakest HClO?

In this case with Cl in them, HClO4 is the strongest, followed by HClO3, and

HClO

is the weakest of the acids with a Cl. (The rule is that if the element is the same in the oxoacid, the more oxygens present, the stronger the acid). Neither HClO4 or HCO3 is the weakest.

Which is stronger acid hclo2 or HClO4?

The oxidation number represents the number of electrons Cl loses. As the oxidation number increases, the charge density of that atom increases such that the atom will strongly pull electron density toward itself (electron withdrawing) from other species near it. This is why

HClO4

will be the strongest acid.

Which is more acidic HClO4 or HIO4?

[Hint :

HClO4 is more acidic than HIO4

. Because Cl is more electronegative than Br due to which ClO3 group have more tendency to withdraw electrons ofO – H bond towards itself as compared to BrO3 group.]

Which is the strongest acid?

The strongest acid is

perchloric acid

on the left, and the weakest is hypochlorous acid on the far right.

Why HClO4 is strong acid than H3PO4?

The

acidic strength increases

in the order hclo4>h2so4>h3PO4. … Stronger acids deprotonate almost completely in water, where weak acids dissociate incompletely in water, making HClO4 a strongest acid among the 3 given acids as the Hydrogen atom dissociates completely.

Why is HClO4 strong acid?

-The given strong acids are HClO4, HNO3 and HCl. … –

The presence of H+ ions disturbs the acidity of the hydrochloric acid

. Means H+ from hydrochloric acid release very quickly but the H+ ions in the solution due to the weak acid (Acetic acid) combines with the counterion of the H+ ion released by hydrochloric acid.

Is HClO4 stronger than HNO3?

HNO3 is a stronger acid than HClO3

; the primary reason is that N is more electronegative than Cl , so it pulls electron density towards itself better. Thus, the H , attached to an outer O , gets less of it and thus the O−H bond is weakened.

Is perchloric acid stronger than hydrochloric acid?

The key difference between perchloric acid and hydrochloric acid is that perchloric acid has hydrogen, chlorine and oxygen atoms whereas hydrochloric acid has hydrogen and chlorine atoms only. …

perchloric acid is extremely acidic

while hydrochloric acid is less acidic compared to perchloric acid.

Is HClO a strong acid?

Strong Acid: dissolves and dissociates 100% to produce protons (H+) 1. seven strong acids: HCl, HBr, HI, HNO3, H2SO4, HClO4, & HClO3 2. … any acid that is not one of the seven strong is a

weak

acid (e.g. H3PO4, HNO2, H2SO3, HClO, HClO2, HF, H2S, HC2H3O2 etc.)
