H2so4 ka value
Web1 day ago · Strong acids have a high value for acid dissociation constant (Ka) and a low value for logarithmic constant (pKa). For example, the Ka and pKa value for H2SO4 is 1 X 103 and -3, respectively. The point to be noted here is that even when H2SO4 is a diprotic acid its Ka and pKa values are calculated only for the first dissociation i.e. one proton.

WebThe pKa value of HCl is approximately -7 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. 30 Kasia Zezula Fordham Finance @Masterworks 8 h Promoted
WebJun 17, 2024 · H X 2 S O X 4 is one of common strong acids, meaning that K X a ( 1) is large and that its dissociation even in moderately concentrated aqueous solutions is almost … WebThe first ionization of H2SO4 is complete. The second ionization is not complete, and has a Ka = 1.2X10^-2. If you are in a very low level chemistry class, you would generally just say that both ionizations are complete. That would make [H+] = 0.50 M. Then, pH = -log (0.50) = 0.30. But this is not true at all.
