A.
K + ions will diffuse from solution A to solution B until the [K + ] of both solutions is 50.5mM
B.
K + ions will diffuse from solution B to solution A until the [K + ] of both solutions is 50.5mM
C.
KCl will diffuse from solution B to solution A until the [K + ] of both solutions is 50.5mM
D.
K + will diffuse from solution A to solution B until a membrane potential develops with solution A negative with respect to solution B
E.
K + will diffuse from solution A to solution B until a membrane potential develops with solution A positive with respect to solution B
