Is HClO4 stronger acid than H2SO4?

…it can be predicted that perchloric acid, HClO4, is a stronger acid than sulfuric acid, H2SO4, which should be a stronger acid than phosphoric acid, H3PO4. For a given nonmetal central atom, the acid strength increases as the oxidation number of the central atom increases.

Why is HClO4 the strongest acid?

In Group 17 oxyacids, electron density is drawn away from the O atom as the electronegativity of the halogen increases. This in turn draws electron density away from the O–H bond and weakens it. The weaker the O–H bond, the stronger the acid.

Why HClO4 is stronger acid than h2so3?

hclo4 is strong because it has greater no oxygen atom. more the oxygen atom more electron will be pulled away from o-h bond and the more this bond will be weakened. between h2so4 and h2 so3 similar reason.

Why HClO4 is more stronger acid than HCL?

explain why HCLO4 is a stronger acid than HCLO. With increase in oxidation number of a particular halogen atom, the acidic character of corresponding oxoacid increases. According to Lowry-Bronsted concept, a strong acid has weak conjugate base and a weak acid has a strongconjugate base.

Is HClO4 strong acid?

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

Why HClO4 is stronger acid than HBrO4?

In fact, perchloric acid is usually considered as the strongest of all simple acids. Among oxoacids of elements of the same group having similar composition, acid strength increases as electronegativity increases. Since chlorine is more electronegative than bromine, HClO4 is a stronger acid than HBrO4.

Is HClO4 stronger oxidising agent?

– In the compound HClO4, chlorine is in +7 oxidation state. – HClO4 with highest oxidation state of chlorine have the greatest tendency to get reduced. – As we know that the compound which gets reduced is an oxidising agent. – So, HClO4 is a stronger oxidising agent.

Why H2SO4 is stronger than H2SO3?

We will rank them based on the number of oxygens and hydrogens in the oxoacid. H2SO4 has more oxygens than H2SO3, the additional oxygen will pull electrons towards itself making the O-H bond weaker. H2SO4 is a stronger acid than H2SO3 because b. it had more oxygens to weaken the H-O bond.

Why is H2SO4 a stronger acid than H2CO3?

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.

Why is HClO4 a stronger acid than HClO4?

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.

Is H2SO4 strong or weak?

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.

Why is HClO4 an acid?

HClO4 is considered an acid because on dissolving in an aqueous solution it dissociates into two ions (H+ and ClO4–) and anything that release proton ion in solution considered as the acid in nature. 1 Why HClO4 is an acid?
