An aqueous solution contains 0.10 M H2S and 0.20 M HCl. If the equilibrium constants for the formation of HS− from
H2S is 1.0×10−7 and that of S2− from HS− ions is 1.2×10−13 then the concentration of S2− ions in aqueous solution is :
As we lerned
Ionization reaction of dibasic acid -
- wherein
are called first and second ionization constant.
