Question

When PbS (s) is treated with warm dilute HNO 3, the products most likely will be (A) Pb 2+, S , NO 2 (B) Pb 2+, S , NO (C) PbO , S , NO (D) PbO 2, SO 42-, N 2

PbS + HNO 3 arrow Pb ( NO 3)2+ S + NO + H 2 O

Q. When $P b S (s)$ is treated with warm dilute $H N O_{3}$ , the products most likely will be

$P b^{2 +}, S, N O_{2}$

$P b^{2 +}, S, NO$

$P b O, S, NO$

$P b O_{2}, S O_{4}^{2 -}, N_{2}$

$P b S + H N O_{3} \to P b (N O_{3})_{2} + S + NO + H_{2} O$
