Stoichiometry In case of a ternery system involving two liquid components and a solute, the ratio of the concentration of the solute in the two phases at equilibrium is called the distribution co-efficient. The distribution co-efficient depends upon the Neither A nor B Solute concentration Temperature Both A & B Neither A nor B Solute concentration Temperature Both A & B ANSWER DOWNLOAD EXAMIANS APP
