K* + 18-crown-6#[complex]*
In methanol solution the equilibrium constant is 1.41 x
10. A similar reaction with Cst has an equilibrium con-
stant of only 2.75 x 104. A solution is made (in methanol)
containing 0.020 mol L each of K* and Cs*. It also
contains 0.30 mol L' of 18-crown-6. Compute the equi-
librium concentrations of both the uncomplexed K* and
the uncomplexed Cs*.
