Question
Three figures are presentedFirst . Mostly contains M2+ 2nd: equal amountsM2+ and X2- 3rd: Mostly containsX2-
The figures above represent the ions in a saturated aqueoussolution of the highly soluble ionic compound MX: MX (s) M2+ + X2-
Questions:
a. Which figure represents a solution prepared by dissolving MX inwater?
b. Which figure represents a solution preppared by dissolving MX ina solution containing Na2X
c. If X2-is a basic anion, which figure representsa saturated solution with the lowest pH?
d. If you were to calculate the Ksp for MX would you get the samevalue in each of the three scenerios?
Why or why no?
Explanation / Answer
Three figures are presentedFirst . Mostly contains M2+ 2nd: equal amountsM2+ and X2- 3rd: Mostly containsX2- .
The figures above represent the ions in a saturated aqueoussolution of the highly soluble ionic compound MX:
MX (s) M2+ +X2- . a)first figure represents a solution prepared by dissolving MXin water. b)Second figure contains equal amounts M2+and X2- figure represents a solutionpreppared by dissolving MX in a solution containing Na2X. c)In figure third maximum amount of X2- so it is having lowest pH.hence it is a acidicnature. d) No .Because in all the cases they have different in theconcentrations they different in their Ksp values. a)first figure represents a solution prepared by dissolving MXin water. b)Second figure contains equal amounts M2+and X2- figure represents a solutionpreppared by dissolving MX in a solution containing Na2X. c)In figure third maximum amount of X2- so it is having lowest pH.hence it is a acidicnature. d) No .Because in all the cases they have different in theconcentrations they different in their Ksp values.
