Suppose a student titrates a 10.00-mL aliquot of saturated Ca(OH)2 solution to the equivalence point with 14.30 mL of 0.0224 M HCl. What was the initial [OH − ]? WebAssign will check your answer for the correct number of significant figures
.064 M 1 Incorrect:
Your answer is incorrect.
What is the experimental value of Ksp?
Homework Answers
Since 1 mole of Ca(OH)2 is completely neutralized by 2 mole of HCl
so, 2X moles of HCl = mole of Ca(OH)2
i.e. 2X14.30 mL X 0.0224 mol /L = 10.00 mLX Molarity (mole/L)
this gives , Molarity = 2X 14.30 X0.0224/10.00 = 0.0641 M
Ksp of CaCl2 can be calculated as: please see the uploaded picture.
