Is HSO4 or H2SO4 a stronger acid?
H2SO4 is a strong acid. When it looses a hydrogen, it becomes HSO4-, and gains a negative charge. HSO4- is the conjugate base of H2SO4 but it can still give its Hydrogen away, and thus it is a weak acid as well. It’s weak because it doesn’t part with its hydrogen as easily as H2SO4 did.
Is HSO4 acidic or basic?
The bisulfate molecule doesn’t exist in solution. I can only find references to the hydrogen sulfate molecule as part of salts, which implies that hydrogen sulfate is usually found as an ion. The bisulfate (hydrogen sulfate) ion is indeed an acid. It is a relatively strong weak acid too, with a Ka value of 1.2∗10−2.
Is H2SO4 considered a strong acid?
Strong acids completely dissociate into their ions in water, while weak acids only partially dissociate. All the other acids are weak. The strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid.
Is H2SO4 a strong acid or a weak acid?
Weak acids are only slightly ionized. Phosphoric acid is stronger than acetic acid and so is ionized to a greater extent….Strong and Weak Acids and Acid Ionization Constant.
| Acid | Conjugate Base |
|---|---|
| HCl (hydrochloric acid) (strongest) | Cl− (chloride ion) (weakest) |
| H2SO4 (sulfuric acid) | HSO4− (hydrogen sulfate ion) |
| HNO3 (nitric acid) | NO3− (nitrate ion) |
| Weak Acids |
Is HSO4 a weak acid?
HSO4- is not a strong acid because it is actually a weak acid. That means that it partially dissociates to make H+ and SO4^2-. However, H2SO4 is a strong acid and completely dissociates to create H+ and HSO4-.
How can HSO4 be an acid and base?
The bronsted lowry acid is the species which donates a proton H+ ion . Now, HSO4- is a base since it has the ability to accept a proton but it is a conjugate base to H2SO4 since it is formed by the H2SO4 after donating a proton.
Is HNO2 a strong acid?
Nitrous acid (HNO2), a weak acid, is very unstable and exists only in aqueous solution.
Why is H2SO4 a weak acid?
Strong acids are 100% ionized in solution. Weak acids are only slightly ionized. Phosphoric acid is stronger than acetic acid and so is ionized to a greater extent….Strong and Weak Acids and Acid Ionization Constant.
| Acid | Conjugate Base |
|---|---|
| H2SO4 (sulfuric acid) | HSO4− (hydrogen sulfate ion) |
| HNO3 (nitric acid) | NO3− (nitrate ion) |
| Weak Acids |
What is the acid for HSO4?
sulfuric acid
The conjugate acid of HSO4 -1 is H2 SO4. Adding one hydrogen ion to the hydrogen sulfate ion generates the conjugate acid. Its name is sulfuric acid.
Can HSO4 act as a base and acid?
The hydrogen sulfate or bisulfate ion, HSO4−, can act as either an acid or a base in water solution.
Why is HSO4 a weaker acid than H2SO4?
H2SO4 is a strong acid. When it looses a hydrogen, it becomes HSO4-, and gains a negative charge. HSO4- is the conjugate base of H2SO4 but it can still give its Hydrogen away, and thus it is a weak acid as well. It’s weak because it doesn’t part with its hydrogen as easily as H2SO4 did. I am a chemistry tutor who has been teaching for over 5 years.
Is H2SO4 a strong or a weak acid?
Weak acid always forms a strong conjugate base. A weak base always forms a strong conjugate acid. So, H2SO4 is a strong acid that makes a weak conjugate base according to the concept of conjugate acid-base pair. The conjugate base of H2SO4 is HSO4-.
Is hc2h3o2 a weak or a strong acid?
Because all of the hydrogen chloride forms separate ions, hydrochloric acid is a strong acid. A weak acid does not form many ions in solution. Acetic acid (HC2H3O2) is the acid in vinegar. Therefore, acetic acid is a weak acid.
Which is the stronger acid, HCl or H2SO4?
This means HCl in an aqueous solution is more deprotonated than HNO3, and so HCl is a stronger acid than HNO3. That’s it. Don’t get confused with those NaCl+H2SO4 situations. HCl is a gas and can be eliminated from the reaction mixture, which allows the reaction to occur, even if HCl is the stronger acid.
