Synthesis
Lead(II) chloride precipitates from solution upon addition of chloride sources (HCl, NaCl, KCl) to aqueous solutions of lead(II) compounds such as Pb(NO3)2.
- Pb(NO3)2(aq) + 2 NaCl(aq) → PbCl2(s) + 2 NaNO3(aq)
- Pb(CH3COO)2(aq) + HCl(aq) → PbCl2(s) + 2 CH3COOH(aq)
- basic PbCO3 + 2 HCl(aq) → PbCl2(s) + CO2(g) + H2O
- Pb(NO3)2(aq) + 2 HCl(aq) → PbCl2(s) + 2 HNO3(aq)
Treatment of lead dioxide with hydrochloric acid gives lead(II) chloride as well as chlorine gas:
- PbO2(s) + 4 HCl → PbCl2(s) + Cl2 + 2 H2O
Treatment of lead oxide with hydrochloric acid gives lead(II) chloride as well as water
- PbO(s) + 2 HCl → PbCl2(s) + H2O
PbCl2(s) also forms by the action of chlorine gas on lead metal:
- Pb + Cl2 → PbCl2

Famous quotes containing the word synthesis:
“In order to begin an analysis, there must already be a synthesis present in the mind.”
—Johan Huizinga (1872–1945)
“The invention of photography provided a radically new picture-making process—a process based not on synthesis but on selection. The difference was a basic one. Paintings were made—constructed from a storehouse of traditional schemes and skills and attitudes—but photographs, as the man on the street put, were taken.”
—Jean Szarkowski (b. 1925)
“The new shopping malls make possible the synthesis of all consumer activities, not least of which are shopping, flirting with objects, idle wandering, and all the permutations of these.”
—Jean Baudrillard (b. 1929)
