Is HSO4- a weak acid?
HSO4- is a weak acid. It is the conjugate base of sulfuric acid (H2SO4), which is a strong acid. However, HSO4- itself is a weak acid and partially dissociates in water.
Is sulphuric acid a strong or weak acid?
Sulfuric acid is considered a strong acid because it ionizes completely in water to form H+ and HSO4- ions. It is highly corrosive and has a low pH.
Is HSe- an acid or base?
HSO4 is Hydrogen Sulphate and an amphiprotic species. It is the conjugate base of H2SO4. H2SO4 is sulphuric acid, a very strong acid.
What is the conjugate acid for HSO4?
H2SO4 is already a strong acid.If you mean what is the conjugate base, then the answer is HSO4-
Is H2SO3 a weak acid?
It is a strong acid only for the first hydrogen ion that is produced. (1) H2SO4 --> H+ + HSO4^- The remaining bisulfate ion, HSO4^-, is a weak acid and only partially dissociates. (2) HSO4^- <==> H+ + SO4^2- A misconception is that since sulfuric acid is a strong acid, that it dissociates like this: (3) H2SO4 --> 2H+ + SO4^2- That simply isn't the case except for extremely dilute solutions. As the concentration of the acid decreases, the acid behaves more and more like a strong diporotic acid. At "infinite dilution" it is accurate to write the dissociation as equation (3).

Weak and strong acids?
A strong acid disassociates completely or nearly completely when diluted with water. A weak acid will not disassociate completely, or even hardly at all. For example, if you have a strong acid solution, such as hydrochloric acid (HCl - a strong acid) and add baking soda, (sodium carbonate), the free hydrogen ions (the H in the HCl) in the solution will bind with the carbonate portion of the sodium carbonate to make Carbonic Acid - a weak acid. Carbonic Acid is weak, so it binds the ions, and lowers the acidity of the solution. The Sodium and Chlorine form table salt, if the solution is dried. The idea here is that the carbonic acid does not completely disassociate in the water - in other words, the hydrogen ion does not separate from the carbonate in water - maybe only 10% will disassociate. HCl is another matter - it's a very strong acid, where 100% of the molecules dissassociate.
IS HIO a strong acid?
H3O is not an acid, it is a base. When undiluted, it is a very strong base, though.
Is hypochlorous acid a strong or weak acid?
Hypochlorous acid is a weak acid. It is a fairly weak acid compared to strong acids like hydrochloric acid.
How do you write the dissociation equation for acid salt 'sodium hydrogen sulfate'?
This dissociation is a two step process: NaHSO4 ---> Na+ + HSO4- HSO4- <---> H+ + SO42- (weak acid protolysis)
Is the conjugate of a strong base is a weak acid?
NaHCO3 is a weak base, with a conjugate acid of H2CO3+.
Is MgCl2 a weak or strong acid?
It is a weak acid
Is hypochlorous acid a strong or weak acid?
Hypochlorous acid is a weak acid.
