Ksp Lab Report: The Solubility Properties of the Salt (Lab Report Sample) Content: NameTutorSubjectDateKsp Lab ReportAbstractDifferent salts have different solubility properties which are also affected by external environmental conditions. This property can be determined experimentally at 00C using chilled water to determine the various values of the Ksp values for the solids. Therefore, this practicals aim is to ascertain the Ksp values of two salts, NaCl, and KCl.IntroductionThe ability of different salts such as those of magnesium, barium, and potassium, just to mention a few, is commonly based on the solubility product constant (Ksp).Therefore, the lower the Ksp value of the salt, the lower its solubility.These experiments can be achieved in the laboratory by having specific amounts of the test salts at temperatures of 00C and recording the amount of cold water required to dissolve the solids. By calculating the molarity values of this dissolved ions, it's possible to measure the Ksp values and measure the degree of solubility.MaterialsPre masse d salts (KCl (s) and NaC l(s) )Mortar and pestle2-250 ml Beakers10.0 ml Graduated Cylinder2 Styrofoam cupsThermometerStirring spoonDistilled waterCrushed iceProcedureThe Dropper Pipette was calibrated using graduated cylinder and the calibration repeated three times. The results were recorded and an average value determined. KCl solid sample was then crushed in a mortar, and the powder poured into a 50 ml beaker placed in a cold water bath. This was followed by dissolving the solid in 2 ml of water and dropwise addition until the whole solid had dissolved.The total volume was the recorded. Three trials were performed following the same process.NaCl was also dissolved following the same procedure and the total volume recorded in a data table.ResultsThe table contains the trail measures during the calibration of the pipette.Trials number Number of drops(1.0 ml) 1 5 2 6 3 6 Average number of drops=5.7 drops =1.0mlCalculationsTrialNumber Originalmass of sample (g) Volume ofwater (mL) ad ded to rinse salt Number ofdrops of water added to saturation Totalvolume (mL) water added Moles ofsalt added Molarity(M) of salt solution NaCl 1 2.5 2 12 2 0.04 20 NaCl 2 2.5 2 12 2 0.04 20 NaCl 3 2.5 2 12 2 0.04 20 KCl 4 2.5 2 12 2 0.03 15 KCl 5 2.5 2 12 2 0.03 15
