Homework Help: Ionic equilibrium - hint needed

  1. Feb 14, 2006 #1
    0.05ml of NH3 is dissloved in a solution containing water followed by 0.27g of NH4Cl. If the Kb for NH4OH is 1.8 * 10^-5 find the pH value of the solution.
    I am finding it difficult to predict the reactions that are going to happen here. I know to calculate Kh or the constant of hydrolysis of NH4Cl from here but how does NH3 dissolve in water. I think it mixes with H+ in the solution to form NH4+.
    But I don't know how to continue.

    This is classical buffer question.

    Compare with this buffer question - not identical, but close.
