The perchloric acid is a strong acid in nature, it is soluble in the water. Perchloric acid is an ionic compound, it acts as a strong electrolyte. Hence, when perchloric acid is dissolved in the water, it dissociates into hydrogen and perchlorate ions.
Is HClO4 an acid or base?

HCl (hydrochloric acid) HNO3 (nitric acid) HClO4 (perchloric acid) H2SO4 (sulfuric acid) | NaOH (sodium hydroxide) KOH (potassium hydroxide) Ca(OH)2 (calcium hydroxide) |
How is HClO4 formed?
NaClO4 + HCl → NaCl + HClO4
Alternately it can be prepared by mixing nitric acid (HNO3) with ammonium perchlorate (NH4ClO4) and add hydrochloric acid while its boiling.
What is the name of the acid formed when HBr gas is dissolved in water?
Hydrobromic acid is a strong acid formed by dissolving the diatomic molecule hydrogen bromide (HBr) in water.
Is perchloric acid polar?
HCLO4 is a polar molecule. The molecule consists of one hydrogen, four oxygen, and one chlorine atom.
What is the name for the acid HClO2?
Chlorous acid | HClO2 – PubChem.
What is the pKa of perchloric acid?
Perchloric acid (HClO4): pKa ≈ -8. Hydrochloric acid (HCl): pKa = -6.3.
Is HClO4 conjugate acid?
Since NH+4 is formed after the base, NH3 , has gained a proton, then that makes NH+4 the conjugate acid. Meanwhile, ClO−4 is the result of HClO4 , the acid, donating its proton, and thus making it the conjugate base.
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?
Why is HClO4 a strong acid?
Hclo4 is more acidic all of the them because Oxygen is more electronegative and shows four different resonating structures. In water both HClO3 and H2SO4 are equally strong acid(Levelling effect). However in other solvent like acetic acid, H2SO4(pKa=- 3) is stronger acid than HClO3(pKa =-1).
Is perchloric acid a binary acid?
Simple acids, known as binary acids, have only one anion and one hydrogen. … Therefore, HClO4 is called perchloric acid. With one fewer oxygen than the “-ate” ion, the acid will have the suffix “-ous.” For example, chlorous acid is HClO2.
Is HBr an acid or base?
Acids | Bases |
---|---|
HCl | LiOH |
HBr | NaOH |
HI | KOH |
HNO 3 | RbOH |
What is the name of the acid formed when h2s gas is dissolved in water?
Dissolved in water, it forms a very weak dibasic acid that is sometimes called hydrosulfuric acid. Hydrogen sulfide is flammable; in an excess of air it burns to form sulfur dioxide and water, but if not enough oxygen is present, it forms elemental sulfur and water.
Is perchloric acid soluble in water?
Perchloric acid (72%, azeotropic mixture with water) is one of the strongest mineral acids and presents a high oxidizing power at high temperature, making it very suitable for the digestion of matrices such as fat, proteins, and lipids as the resulting perchlorates are readily soluble in water.
What is the name of HNO2?
Nitrous acid (HNO2), a weak acid, is very unstable and exists only in aqueous solution.
What is the Ka value of HClO4?

What acid is formed from the bromide ion?
The acid formed from the bromide ion is HBr or hydrobromic acid.
Why is HClO2 named Chlorous acid?
2) HClO2 has the ClO2¯ polyatomic ion in it. The name of this ion is chlorite. Since the “ite” suffix is used, it gets changed to “ous.” The name of HClO2 is chlorous acid.
What is the conjugate base of HClO4 and H2O?
In this equation HClO4 has donated a proton to H2O so HClO4 is acting as an acid and as H2O is accepting a proton so H2O is a base. ClO4- on the other side can accept a proton so ClO4- is a base but its a conjugate base to acid HClO4 since it is generatd by losing a proton from HClO4 .
Is HClO4 and Cl A conjugate acid base pair?
– and HPO4 2– represent a conjugate acid–base pair. acid HClO4; the conjugate acid of Cl– is HCl.
Is HClO4 Brønsted-Lowry acid?
Bronsted Acid is HCLO4 because it donates or loses a proton(H) and Becomes Conjugate Base (ClO4) and H2O is a base because it accepts a proton(H) and Becomes Conjugate Acid(H3O).
Is K2SO4 an acid or base?
Potassium Sulphate(K2SO4) is prepared by combining KOH(potassium Hydroxide) and H2SO4(Sulphuric Acid). As H2SO4 is a strong acid and KOH is a strong base,so K2SO4 is a neutral salt.
Why is HClO4 an Arrhenius acid?

Is HClO4 a strong acid in aqueous solution?
HClO4, HNO3 and HCl are all very strong acids in aqueous solutions.
Which is strong 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 the strongest acid HCl or 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 HBrO4 or HClO4?
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.
How do you name a ternary acid?
- The name of the most common oxyacid for a particular nonmetal is the root of the element’s name plus the suffix ic. …
- The name of the acid in which the nonmetal has the next lower oxidation number is the element’s root plus the suffix ous.
What is ternary acid?
Ternary acids are also known as “Oxy-acids. Contain hydrogen and oxygen and one other (usually) nonmetallic element. These acids contain both hydrogen and oxygen but their names make no reference to either hydrogen or oxygen.
Is H2O binary or ternary?
Binary molecular compounds are composed of only two elements. Examples are H2O, NO, SF6 etc. .
