Tods EQUL0400: Eatimacing the Solubility Product Constant of Strontium ledate Using Microscale Technique 228 3. A student used the techniques in this module to estimate the Kp of lead iodide (Pbl). After preci- pitating and rinsing Pbl2 in a reaction pipet, the student equilibrated the solid in distilled water. The cquilibrium reaction is shown in Equation 18 (Eq. 18) Pbla(s)Pb(aq) +21 (aq) The student analyzed 30 drops of the supernatant liquid for Pb ion by titrating it with 28 drops...

An electrochemical cell was designed in order to determine the solubility product constant, Ksp for PbCO2. The cell uses the half reactions shown below to produce the overall dissociation reaction. cathode reaction: anode reaction: overall reaction: PbCO2 (s) + 2e → Pb(s) + CO - (aq) Pb(s) + Pb2+ (aq) + 2 e- PbCO3(s) — Pb2+ (aq) + CO2 (aq) Which equality correctly represents the relationship between the equilibrium constant expression for the overall reaction and the solubility product constant...
