Homogeneous Precipitation

Two precipitates of PbCrO4 are shown in this photo. The precipitate in the beaker on the left was formed by pouring quickly a solution 0.1 M Pb(NO3)2 into a solution of 0.1 M K2CrO4. The precipitate forms rapidly and consists of … Continue reading

Lattice Structure for AgCl

Ball-and-stick diagram showing the lattice structure of AgCl. Each silver ion in the lattice’s interior binds with six chloride ions, and each chloride ion in the interior binds with six silver ions. Those ions on the lattice’s surface or edges … Continue reading

Solubility of AgCl

Illustration showing the solubility of AgCl, SAgCl, as a function of pCl. The dashed red line shows SAgCl if one assumes incorrectly that the only relevant reaction is AgCl(s) ↔ Ag+(aq) + Cl–(aq) The solid blue curve is the actual solubility when considering … Continue reading
