Question

many or tnese questions must be answerea in oraer For this first section of the PostLab you will refer to your data from Table 12-1 provided below Trial #1 Trial #2 0220 M.0220 M 10.0 mL 10.0 mL Volume of HCI added from the buret 15.42 mL 15.48 mL Molarity of HCI Volume of Ca (OH)2 Table 12-1 1. Calculate the molar solubility of Ca(OH)2 in water for each trial Trial #1 Trial #2 mol/L molar solubility of Ca(oH)2 in your d mol/L Please check your data again and re-do the calculation Submit Please review your entries and make corrections where necessary

Explanation / Answer

A/c to MaVa = MbVb

Mb = MaVa/Vb

Trail 1 : Mb =0.22x15.42/10

Mb= 0.339 M

Trail 2 : Mb = 0.22x 15.48/10

Mb = 0.34 M

Ma, Va are Molarity and volume of acid, HCl

Mb, Vb are Molarity and volume of base, Ca(OH)2
