What is the pKa of H2SO4?
What is the pKa of H2SO4?
Sulfuric acid (H2SO4): pKa1 ≈ -3 (first dissociation only) p-Toluenesulfonic acid: pKa = -2.8.

What is the name of the ion HSO4?
hydrogen sulfate
The HSO4- ion is commonly referred to as hydrogen sulfate (which is also called the bisulfate ion). H2SO4 can be called dihydrogen sulfate (but it is popularly known as sulfuric acid).
Is HSO4 strong or weak?
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-.
Which is a stronger base, HSO4 or H2PO4?
An acid is an H+ donor while a base is an H+ acceptor. When looking at HSO4- and H2PO4- it can be said that since HSO4 gives up an H+ easier it is a better acid than H2PO4-. Then it can also be said that H2PO4- is then a better or stronger base than HSO4-. 0.0. 0 votes.
What is the pKa value of H2SO4?
The pKa value of H2SO4 is approximately -3. The pKa value of HNO3 is approximately -1.3. So HCl is strongest of all. There are some super acids, like fluroantimonic acid, that are 100 times more stronger than sulfuric acid.
What is the pKa of hydrochloric acid?
More precisely, the acid must be stronger in aqueous solution than a hydronium ion (H +), so strong acids have a pKa < -1.74. An example is hydrochloric acid (HCl), whose pKa is -6.3.
What is the pKa of hc2h3o2?
The pKa of acetic acid, HC2H3O2, is 4.76. A buffer solution was made using an unspecified amount of acetic acid and 0.30 moles of NaC2H3O2 in enough water to make 1.50 liters of solution. Its pH was measured as 4.50 on a meter.
