WebS135: Chemical Rxns – Precipitation – Pb (NO3)2 + KI → PbI2 (s) Introduction A 100mm petri dish containing water is placed on an overhead projector. When solid Pb (NO 3) 2 is place on one side and solid KI on the other, PbI2 precipitates in the center. Pb (NO 3) 2 (aq) + 2KI (aq) → PbI 2 (s) + 2KNO 3 (aq) To Conduct Demonstration WebMar 16, 2024 · The pH scale (pH) is a numeric scale used to define how acidic or basic an aqueous solution is. It commonly ranges between 0 and 14 but can go beyond these values if sufficiently acidic/basic. The pH value is logarithmically and is inversely related to the concentration of hydrogen ions in a solution.
