Question
Titration of Calcium Hydroxide with HCl Solution
Mass of CA
10.70 mL
Molarity of the HCl Solution?
Calculate
From the masses, determine the molesof Ca in each sample.
________ mol _____________mol Ca
From the MLs and molarity of HCl, calculate hte moles of HCl used in the titration of each sample
_______ mol ____________ mol HCl
From the moles of HCl and the stoichiometry of the reaction between OH-1 and HCl given in the introduction, determine the moles of OH-1 in each sample
_______ mol ___________ mol OH-1
From the moles of Ca and OH-1 calculated above, determine the mole ratio of OH-1/Ca for each sample
______________ ______________
Determine the average mole ration of OH-1/Ca
_________________________
From the mole ratio, determine the formula of calcium hydroxide

Sampe 1 Sample2 Mass of Ca 0.810 g 0.870 Final Buret Reading 10.70mL 22.51mL Initial Buret Reading 0.00 g10.70 mL
Titration Volume 10.70 mL 11.81 mL Molarity of HCl solution ???? MExplanation / Answer
No of mol of ca sample 1 = 0.810/40 = 0.02025 mol
No of mol of ca sample 2 = 0.87/40 = 0.02175 mol
for the rest of the part standard data is needed
Ex.
No of mol of HCl = Molarity of HCl *Volume in L
