What is the pH of HClO4?
Answer and Explanation: The pH of a 1.4 M solution of HClO4 is -0.15. Perchloric acid, or HClO4 is a strong acid. It dissociates completely into…
Is HClO4 a strong acid?
The 7 common strong acids are: HCl, HBr, HI, HNO3, HClO3, HClO4 and H2SO4 (1st proton only).
What is the pH of 0.1 m HClO4?
pH = 1.1 In the case of 0.1 M HClO4 (pH = 1.1), which is the electrolyte most usually reported on the literature, the onset potential in the presence of bromide is significantly displaced to more negative potentials.
What is the pH of a 0.0045 M solution of HClO4?
What is the pH of a 0.0045 M solution of HClO4? 2.49 | Chegg.com.
Is hclo4 an acid or base?
HClO4 is a strong acid. Because it readily dissociates in an aqueous solution, which means no dissociated parts of it remain in the solution, all parts completely break off and are ionized in an aqueous solution.
What is the pH of HClO?
HClO has pKa =7.53.
Is HClO4 a base or acid?
Strong Acids
| Strong Acids | Strong Bases |
|---|---|
| HCl (hydrochloric acid) HNO3 (nitric acid) HClO4 (perchloric acid) H2SO4 (sulfuric acid) | NaOH (sodium hydroxide) KOH (potassium hydroxide) Ca(OH)2 (calcium hydroxide) |
What is basicity of HClO4?
2.
How do you find the pH from molarity of hclo4?
1 Answer
- We use the pH equation, which states that,
- pH=−log(H+)
- And so, the pH will be,
- pH=−log(0.075)
- ≈1.12.

Is HCL or HClO4 a stronger acid?
The HClO4 has the most oxygen atoms so it would have to be the strongest acid.
Is HOCl and HClO the same?
Hypochlorous acid (HClO, HOCl, or ClHO) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO−. HClO and ClO− are oxidizers, and the primary disinfection agents of chlorine solutions.
What is the pKa of HClO?
Hypochlorous acid, HClO, has a pKa of 7.54.
Which acid is stronger HCL or HClO4?
The HClO4 has the most oxygen atoms so it would have to be the strongest acid.
Is HClO4 an acid or base?
HClO4 is a strong acid. Because it readily dissociates in an aqueous solution, which means no dissociated parts of it remain in the solution, all parts completely break off and are ionized in an aqueous solution.
Why is HClO4 the strongest acid?
Since the identity of the central atom is the same chlorine as is the number of hydrogens compare the number of oxygen atoms. The HClO4 has the most oxygen atoms so it would have to be the strongest acid.
Why HClO4 is the strongest acid?
The HClO4 has the most oxygen atoms so it would have to be the strongest acid.
Which is the strongest acid HClO4 HClO3 HClO2 HClO HF?
And electronegativity of chlorine in turn is directly proportional to the oxidation state of chlorine. Thus, the order of acidic strength is HClO < HClO2 < HClO3 < HClO4 As the number of oxygen atoms attached to chlorine increases, acid strength increase. Hence, the correct option is (2).
What is the pH of HOCl?
Methods: Stabilized HOCl is in the form of a physiologically balanced solution in 0.9% saline at a pH range of 3.5 to 4.0. Chlorine species distribution in solution is a function of pH. In aqueous solution, HOCl is the predominant species at the pH range of 3 to 6.
What is the pKa of hclo4?
−15.2 Perchloric acid
| Names | |
|---|---|
| Boiling point | 203 °C (397 °F; 476 K) (azeotrope) |
| Solubility in water | Miscible |
| Acidity (pKa) | −15.2 (±2.0); ≈ −10 |
| Conjugate base | Perchlorate |
Why HClO4 is more acidic than HClO?
HClO4 is a stronger acid than HClO. This is because ClO−4ClO4- is a weaker conjugate base than ClO−. In ClO−4ClO4-, the negative charge is spread over four oxygen atoms owing to resonance. Hence, it is more stable than ClO−.
Which is more acidic HClO4 or H2SO4?
oxyacids. …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 more acidic HClO or HClO4?
And electronegativity of chlorine in turn is directly proportional to the oxidation state of chlorine. Thus, the order of acidic strength is HClO < HClO2 < HClO3 < HClO4 As the number of oxygen atoms attached to chlorine increases, acid strength increase.
Which is stronger HClO or 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.
Which is more acidic HClO4 or HClO?
And electronegativity of chlorine in turn is directly proportional to the oxidation state of chlorine. Thus, the order of acidic strength is HClO < HClO2 < HClO3 < HClO4 As the number of oxygen atoms attached to chlorine increases, acid strength increase.
Why is HClO4 more acidic than HClO3?
Assertion: HClO4 is a stronger acid than HClO3. Reason: Oxidation state of chlorine in HClO4 is +7 and in HClO3 is +5.
Is HClO an acid or base?
weak acid Hypochlorous acid (HClO, HOCl, or ClHO) is a weak acid that forms when chlorine dissolves in water, and itself partially dissociates, forming hypochlorite, ClO−.
Which acid is stronger HCl or HClO4?
The HClO4 has the most oxygen atoms so it would have to be the strongest acid.
Which is more acidic HClO4 or HClO3?
HClO4 is a stronger acid than HClO3 .
Which is a stronger acid HClO4 or HClO3?
HClO4 is stronger than HClO3. The oxidation number of Cl in HClO4 is +7 and in HClO3 is +5. The acid strength of oxyacid of the same halogen increases with the increase in oxidation number of halogen.
