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:
“It is in this impossibility of attaining to a synthesis of the inner life and the outward that the inferiority of the biographer to the novelist lies. The biographer quite clearly sees Peel, say, seated on his bench while his opponents overwhelm him with perhaps undeserved censure. He sees him motionless, miserable, his head bent on his breast. He asks himself: “What is he thinking?” and he knows nothing.”
—Andre Maurois (1885–1967)
“In order to begin an analysis, there must already be a synthesis present in the mind.”
—Johan Huizinga (1872–1945)
“It is not easy to construct by mere scientific synthesis a foolproof system which will lead our children in a desired direction and avoid an undesirable one. Obviously, good can come only from a continuing interplay between that which we, as students, are gradually learning and that which we believe in, as people.”
—Erik H. Erikson (20th century)
