\(EAN\ of\ Ni = 28 - 0 + 4 \times 2 = 34\)
\(EAN\ of\ SC^3 = 21 - 3 + 6 \times 2 = 30\)
\(EAN\ of\ Fe^{2+} = 26 - 2 + 6 \times 2 = 36\)
\(EAN\ of\ CO^{3+} = 27 - 3 + 6 \times 2 = 36\)
$1\, L \,of\, X + Excess\, of\, AgNO_3 \rightarrow Y\, mol\, of\, ppt.$
$1\, L\, of\, X + Excess\, of\, BaCl_2 \rightarrow Z\, mol\, of\, ppt.$
તો $Y$ અને $Z$ અનુક્રમે ............... થશે.
