Pre Lab Molarity Solubility

Based on the volumetric glassware used in this experiment (a 50-mL-graduated cylinder and a buret). Select the incorrect data below.

Volume of titrant dispensed = initial buret reading - final buret reading = 50.00 mL- 19.24 mL = 30.76 mL

Volume of the analyte: 25 mL

Initial buret reading: 50.00 mL

There are two solutions: calcium hydroxide in DI water and in a calcium chloride solution. Both contain the maximum amount of dissolved Ca(OH)2. Select the correct statements below.

The molar solubility of calcium hydroxide in DI water is larger than that in the calcium chloride solution.
