Question

The first ionization constant of H₂S is 9.1 × 10^-8. Calculate the concentration of HS^– ions in its 0.1 M solution. How will this concentration be affected if the solution is 0.1 M in HCl also? If the second dissociation constant of H₂S is 1.2 × 10^-13. Calculate the concentration of S^2- under both conditions.

Answer 1

To calculate the concentration of HS^– ion.
Case I: In case of absence of HCl
