When an ionic compound dissolves in water, the cations and anions are separated. Ions in solution will result in that solution conducting electricity, an electrolyte. Some solutions are strong electrolytes while others are weak electrolytes. 1. What do you think is giving rise to electrical conductivity? ions in a crystal 2. This is a diagram showing ions in a crystal. Draw a diagram showing the particles in 1) strong electrolyte, and 2) weak electrolyte. Pay attention to how the water...

Experiment 8 Solubility of lonic Precipitates Lead chloride is a slightly soluble salt. When lead chloride dissolves in pure water or an aqueous solution, the small quantity that dissolves completely ionizes and reaches equilibrium in a saturated solution, PbCl(s) ® Pb (aq) + 2Cl(aq) Kp = [Pb (C) (1) Lets be the molar solubility of lead chloride. In pure water, s = [Pb ) = (CH) / 2. In a solution containing Cl, a common ion to lead chloride, s...
