Explain how the calculation of the molar solubility will be affected if a small amount of the sample adhering to the side of the flask was left unreacted when the end point was thought to have been reached. Procedure: Pipet 25 mL of the saturated Ca(OH)2 solution (without added CaCl2) into a 125 mL flask and add 2 drops of methyl orange indicator. Titrate the Ca(OH)2 solution to the methyl orange endpoint, where the color changes from yellow to red. Titrate two additional 25 mL aliquots of the saturated Ca(OH)2 solution

Javier mixes 20.00 mL of 0.500 M Pb(NO3)2 and 30.00 mL of 0.250 M NaCl in hopes of making precipitate like all his other AP Chemistry friends! Did he do it? Did he make a precipitate? The Ksp of the possible precipitate is 1.6x10-5
