Which is the strongest acid HClO HClO2 HClO3 HClO4?
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 HClO4 stronger than HClO3?
HClO4 (perchloric acid) is a stronger acid than HClO3 (chloric acid). In fact, HClO4 is generally regarded the strongest of all known simple acids. Both HClO4 and HClO3 are oxyacids of chlorine, and the oxidation number of chlorine in them are +7 and +5 respectively.
Is HClO3 stronger than HBrO3?
Chlorine being more electronegative than Bromine it pulls the electron of hydrogen more strongly and hence has a higher tendency to release a H+ unit. Hence we can say that HClO3 is more acidic than HBrO3. This is also evident from the lower pKa value of HClO3(-1) vs that of HBrO3(0.7).
Is HBrO4 stronger than HBrO3?
The pKa of HBrO3 is -2 and of HBr04 is -4.6. This means that both are strong acids, completely ionized in water. HBrO4 is a stronger acid than HBrO3 by over 2 orders of magnitude.
Why is HClO4 stronger than HClO3?
The general rule is that the acid is stronger if it has more O atoms in a series such as this. HClO4, perchloric acid, is a very strong acid as is HClO3. HClO2 is a weak acid and HClO is even weaker. … Thus we see more oxygen atoms means more possible strutures & which means stronger the acid.
Is HBrO4 a strong acid?
Perbromic acid is a strong acid and strongly oxidizing. It is the most unstable of the halogen(VII) oxoacids. It decomposes rapidly on standing to bromic acid and oxygen. It reacts with bases to form perbromate salts.
Is HClO4 a strong acid?
The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only). … They simply do not ionize completely whereas a strong acid or base does.
Is HClO2 a weak acid?
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.) … solutions of weak acids have a low concentration of H+. 3. the molecular form of the weak acid does exist in solution.
Is Hi a strong acid?
HCl, HBr, and HI are all strong acids, whereas HF is a weak acid. The acid strength increases as the experimental pKa values decrease in the following order: … Hydrochloric acid: Hydrochloric acid is a clear, colorless solution of hydrogen chloride (HCl) in water.
Is hio4 stronger than HClO4?
The atom which has greater tendency to give a proton or H+ is stronger acid. … The Hydrogen atom in HClO4 will experience less attraction to Oxygen than in HIO4 (the electron is further). That’s why HClO4 is stronger than HIO4.
Why is perchloric acid strong?
In general, delocalization of electrons makes the molecule more stable. Perchloric acid has three of such double bonds, while sulfuric acid has only two. Thus, the conjugate base of perchloric acid is more stable, meaning the acid itself is more acidic.
Why is HClO4 the strongest acid?
hope it helps!! 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.
