Question

State True or False.

Lead comes in group I as well as group II.

• A. True
• B. False

Answer 1

The correct option is B False

Lead is precipitated in Group I as $PbC{l}_2$ . Since it is partly soluble in water, a part of its goes into the filtrate which is to be tested for group II radicals. Thus, on passing $H_{2}S$ gas, it gives a black ppt. of PbS.
$P{b}^{+2}+H_{2}S\to PbS+2H^{+}$
