Consider the following data for question 1-6: Two solutions of an unknown slightly soluble salt, A(OH)2, were allowed to equilibrate -- one at 25oC and the other at 80 oC. A 15.00 mL aliquot of each solution is titrated with 0.200 M HCl. 9.00 mL of the acid is required to reach the endpoint of the titration at 25 oC, while 74.35 mL are required for the 80 oC solution.
Calculate the Ksp at 25 oC.
Homework Answers
Answer:
To calculate the Ksp at 25
Reaction is given as follows
HCl moles = molarity * volume
= 0.200 * 9
= 1.8 mmol
Here it is given that 15 ml aliquot is titrated with HCl
2X * 15 = 1.8 mmol
X = 0.06M
Now ,
Ksp = [A+][OH-]^2
= x*(2x)^2
= 4x^3
= 4(0.06)^3
Ksp = 0.000864
