Which is the strongest acid hclo4 H2SO4 HNO3 HCl?
HCl is the strongest acid (indicated by the lowest pKa) followed by H2SO4 and HNO3. H3PO4 is the weakest of the acids.
Which of the following is strongest acid HCl hclo3 HNO3 H2SO4 hclo4?
Hre HCLO4is the strongst acid. reason between hclo3 abd hclo4 . 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.
Which is a stronger acid H2SO4 or hclo4?
…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.
Which is strong acid hclo4 or HNO3?
HClO4, HNO3 and HCl are all very strong acids in aqueous solutions.
Which is stronger H2SO4 or HNO3?
H2SO4 is not “stronger” than HNO3, it is simply more corrosive and non volatile. When compared on the pH scale, H2SO4 is found to be more acidic than the hydronium atom, whereas HNO3 has a lesser pH that hydronium. Also H2SO4 has 2 hydrogen atoms as oppossed to HNO3 which has only 1 H.
Is HCL a stronger acid than HNO3?
Yes, hydrochloric acid is stronger than nitric acid. This is due to the deprotonation of hydrochloric acid in aqueous form. This makes hydrochloric acid stronger than nitric acid.
Which of the following is strongest acid HClO4?
The HClO4 has the most oxygen atoms so it would have to be the strongest acid. The acidic strength of oxoacids of chlorine is in the order ‘HClO4,HClO3,HClO2,HClO’ Briefly explain the reason for this.
Which is stronger acid HNO3 or H2SO4?
Strength or acidity of an acid depends on how easily it loses its proton(s) in aqueous environment. Dissociation constant of H2SO4 (pKa=-3) is more negative than that of HNO3 (pKa=-1.38) that means H2SO4 releases protons more easily than HNO3. Therefore H2SO4 is stronger acid that HNO3.
Which is strong acid HNO3 or H2SO4?
Which is more acidic HCl or H2SO4 or HClO4?
Hclo4 is more acidic all of the them because Oxygen is more electronegative and shows four different resonating structures. Originally Answered: Which is a strong acid HCl, H2SO4, H2NO3, or HClO4? Hydrochloric acid, sulphuric acid and perchloric acid are all strong acids.
Why is HClO3 a stronger acid 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. Weaker bond = stronger acidity. Setting aside the ones we picked, the remaining ones are:
Is H2CO3 a strong or weak acid?
H2CO3—Carbonic acid is weaker as it ionises partially to produce lesser hydrogen ions per mole of the acid in aqueous solution. The strength of an acid refers to its ability or tendency to lose a proton, or an H⁺ ion. A strong acid is one that completely ionises in solution state.
What is the pKa of H2SO4?
For pKa2 (HSO4-) it is a weaker acid. But, it is the first pKa that is important, H2SO4 wins on the basis of pKa. Just to confuse things, pubchem ( SULFURIC ACID | H2SO4) claims that the pKa of H2SO4 is 1.92 (not -1.92, +1.92) and nitric acid ( NITRIC ACID | HNO3) pKa is -1.38.
