MY and ``NY_3``, two nearly insoluble salts, have the
same ``K_{sp}`` values of 6.2 × ``10^{-13}`` at room
temperature. Which statement would be true in
regard to MY and ``NY_3`` ?
(1) The molar solubilities of MY and ``NY_3`` in water
are identical.
(2) The molar solubility of MY in water is less than
that of ``NY_3``
(3) The salts MY and ``NY_3`` are more soluble in
0.5 M KY than in pure water.
(4) The addition of the salt of KY to solution of MY
and ``NY_3`` will have no effect on their solubilities.
