Question

describe how a solid sample of lead (ii) chloride can be prepared using the following reagents. Dilute nitric acid, dilute hydrochloric acid and lead (ii) carbonate

Answer 1

Answer:

Explanation:

PbCO 3 ( s ) + 2HCl(g) → PbCl 2 ( s ) + 2 CO 3 ( aq )  Carbonicacid ( H2 CO 3 ) isunstabledecomposes:

H 2 CO 3 ( aq ) → H O( l ) + CO ( g )  The overall reaction is:

 PbCO 3 ( s ) + 2HCl(g) →PbCl 2 ( aq ) + H2 O( l ) + CO 2( g )
