Question

List as many experimental techniques as you can that may be used to determine Ksp for a sparingly soluble salt. Select all that apply.

a) Determine the concentration of ions in a saturated solution with a titrimetric procedure and use this value to calculate the Ksp.
b) Determine the concentration of ions in a saturated solution with an electrical conductivity measurement and use this value to calculate the Ksp.
c) Evaporating a given volume of a saturated solution of salt and finding the mass of the salt that dissolved to directly find the Ksp.
d) Determine the concentration of ions in a saturated solution with an EMG procedure and use this value to calculate the Ksp.
e) Determine the concentration of ions in a saturated solution with a colorimetric procedure and use this value to calculate the Ksp.

Answer 1

Answer: a) and b)

Explanation:

We can both use titrimetric method and electrical conductivity meter meter to determine the concentration of the ions after which we can calculate the value of Ksp

Answer 2

Using a titrimetric technique, determine the ion concentration in a saturated solution and use this number to compute the Ksp.

Experimental techniques and Ksp:

Using an electrical conductivity measurement, determine the ion concentration in a saturated solution and use this number to compute the Ksp.

To directly find the Ksp, evaporate a precise volume of a saturated salt solution and find the weight of the salt that dissolved.

Using an EMG method, determine the ion concentration in a suitable solvent and use this number to compute the Ksp. Using a colorimetric technique, determine the ion concentration in a saturated solution and use this number to compute the Ksp.
