Question

$Pb+2KOH(hotconc.)$$\to$___+___

• A. $K_{2}Pb{O}_2$
• B. $H_2$
• C. PbO
• D. $Pb(OH{)}_2$

Answer 1

Answer: (A), (B)

The correct options are
A

$K_{2}Pb{O}_2$

B

$H_2$

Lead reacts with hot concentrated caustic alkalis to give the corresponding soluble salt and liberate hydrogen. Here, lead reacts with hot concentrated potassium hydroxide to produce potassium plumbite ($K_{2}Pb{O}_2$) and liberate hydrogen.
