An aqueous solution of an unknown, monobasic weak base has an initial molarity of .176 M and a final[OH-] of .0000158 M. What is the Kb of the unknown base?

  • Chemistry - ,

    NH3 + HOH ==> NH4^+ + OH^-

    Kb = (NH4^+)(OH^-)/(NH3)
    Isn't this just a matter of substituting into Kb expression and solving for Kb?
