MCQ
For saturated solution of $CaF_2$, choose the correct relationship-
  • A
    $\Lambda _{{m_{Ca{F_2}}}}^\infty  = \lambda _{e{q_{C{a^{2 + }}}}}^\infty  + 2\lambda _{e{q_{{F^\Theta }}}}^\infty$
  • ✓
    $\Lambda _{{m_{Ca{F_2}}}}^\infty  = 2\left( {\lambda _{e{q_{C{a^{2 + }}}}}^\infty  + \lambda _{e{q_{{F^\Theta }}}}^\infty } \right)$
  • C
    $\Lambda _{{m_{Ca{F_2}}}}^\infty  = 2\left( {\lambda _{e{q_{C{a^{2 + }}}}}^\infty  + 2\lambda _{e{q_{{F^\Theta }}}}^\infty } \right)$
  • D
    $\Lambda _{{m_{Ca{F_2}}}}^\infty  = \frac{1}{2}\left( {\lambda _{e{q_{C{a^{2 + }}}}}^\infty  + \lambda _{e{q_{{F^\Theta }}}}^\infty } \right)$
✓
