Question

A student performed this experiment, but incorrectly used a beaker to find the volumes, rather than a graduated cylinder. If all of the volume measurements (of the dissolved solutions) were too big each time, what would be the effect on the student's calculated Ksp?

Question 6 options:

Calculated Ksp would be too big.

Calculated Ksp could be too big or too small.

Calculated Ksp would still be correct.

Calculated Ksp would be too small.

Calculated Ksp could be too big or too small.

Calculated Ksp would still be correct.

Calculated Ksp would be too small.

Explanation / Answer

consider salt may be AB --------> A+ +B-

Ksp = [A+] [B-]

so Ksp is directly proportional to Concentration i.e., mol / L or inversely proportional to volume of solution.

Since student used beakers for measuring of volumes they may be less than or more than exact volumes. So the Ksp value also changes with respect to the volume of the solution.

Hence calculated Ksp would be too big or too small.
