$(i)$ $\left[ M ( NCS )_{6}\right]^{(-6+ n )}$
$(ii)$ $\left[ MF _{6}\right]^{(-6+ n )}$
$(iii)$ $\left[ M \left( NH _{3}\right)_{6}\right]^{ n ^{+}}$
$1\, L \,of\, X + Excess\, of\, AgNO_3 \rightarrow Y\, mol\, of\, ppt.$
$1\, L\, of\, X + Excess\, of\, BaCl_2 \rightarrow Z\, mol\, of\, ppt.$
તો $Y$ અને $Z$ અનુક્રમે ............... થશે.
