Question
Consider a saturated solution of the salt MX3, which M is a metal cation with a 3+ charge and X is an anion with a 1 charge, in water at 298 K. Which of the following will affect the Ksp of MX3 in water? Consider a saturated solution of the salt , which is a metal cation with a charge and is an anion with a charge, in water at 298 . Which of the following will affect the of in water? raising the temperature of the solution the addition of more M3+ to the solution the addition of more X to the solution more than one of the above factors diluting the solution
Explanation / Answer
MX3 --> M3+ + 3X-
Ksp = [M3+] [X-]3
Like all equilibrium constants, the Ksp is temperature dependent, but at a given temperature it remains relatively constant.
1) Raising temperature of the solution will affect Ksp
2) No change in Ksp on addition of either cation M3+ or anion X-.
