Is perchloric strong or weak?
Perchloric acid (HClO4) is one of the strongest mineral acids. Hot and concentrated perchloric acid has powerful oxidizing and dehydrating properties, and it will react explosively with organic compounds.
Is HClO4 stronger than HClO?
HClO4 is a stronger acid than HClO. This is because ClO−4ClO4- is a weaker conjugate base than ClO−. Hence, it is more stable than ClO−.
Is HClO4 or HOCl a stronger acid?
Most acidic: HClO4 > HClO3 > HClO2 > HClO. For a series of oxyacids with the same number of oxygens but with different central atoms such as HOBr, HOCl, HOI, as the electronegativity of the central atom increases, the O-H bond strength weakens and the acidity increases. Most acidic: HOCl > HOBr > HOI :Least acidic.
Is CL a weak base?
A strong acid like HCl donates its proton so readily that there is essentially no tendency for the conjugate base Cl– to reaccept a proton. Consequently, Cl– is a very weak base.
Which is the stronger base Cl or h2o?
The general rules suggest that the stronger of a pair of acids must form the weaker of a pair of conjugate bases. The fact that HCl is a stronger acid than the H3O+ ion implies that the Cl- ion is a weaker base than water.
Is HClO4 an ionic compound?
Perchloric AcidPerchloric acid / IUPAC ID
Why is HClO4 a strong acid?
Since chlorine is more electronegative than bromine, HClO4 is a stronger acid than HBrO4. HClO4 is more acidic than HNO3. To compare the acidic strength of any acid, we compare the stability of the conjugate base or the anion formed after loosing the acidic hydrogen.
Why HClO4 is a strongest acid?
Greater the number of negative atoms present in the oxy-acid make the acid stronger. In turn, the electrons of H−O bond are drawn more strongly away from the H-atom. The net effect makes it easier from the proton release and increases the acid strength.
Which HClO is strongest?
The strongest acid is perchloric acid (HClO4 ). When comparing the strength of oxoacids, the ones containing the non-hydrogen and…
Why is HClO4 the strongest acid?
Why HClO4 is stronger acid than HCl o2?
First the H+ in HClO4 is not attached to Cl but O. Here the acidity of HClO4 is stronger than HCl due to the reason that [ClO4]- is more stable than Cl-. ( More electronegative O atom will pull electrons away from the O-H bond.)
Which acid is stronger HCl or HClO4?
HClO4 (perchloric acid) is a stronger acid than HClO3 (chloric acid). In fact HClO4 is considered to be the strongest of all known acids. Both HClO4 and HClO3 are oxyacids of chlorine, and the oxidation number of chlorine in them are +7 and +5 respectively.
Is HClO a strong or weak electrolyte?
Acetone , CH3COCH3 , is a nonelectrolyte; hypochlorous acid, HClO, is a weak electrolyte as well as ammonium chloride, NH4Cl is a strong electrolyte.
Is ClO4 a stronger acid than HClO3?
Assertion: HClO 4 is a stronger acid than HClO 3. Reason : Oxidation state of Cl in HClO 4 is +8 and in HClO 3 +5. If both assertion and reason are false. Greater the number of negative atoms present in the oxy-acid make the acid stronger.
Which is the strongest acid, HClO4 or HBrO3?
Among these three acids HClO3 is the strongest acid, with greatest Ka and lowest pKa value (-1), Then comes HBrO3, its the second most strongest acid among the three, its Pka value is 0.7, higher than HClO3 but smaller than HIO3 (i. e. 0.77) which the weakest acid among the three.
