Question
Consider a saturated solution of CaCl2. Which of the 3 processes will happen under each given circumstance?
Circumstance 1: more calcium ion is added to the mixture? Circumstance 2: more sodium chloride is added to the mixture? Circumstance 3: more water is added to the mixture? Circumstance 4: more solid calcium chloride is added to the mixture?
Process 1: The reaction will spontaneously start producing aqueous ions. Process 2: The reaction will remain at equilibrium. Process 3: The reaction will spontaneously start producing solid calcium chloride.
Explanation / Answer
Circumstance 1: more calcium ion is added to the mixture? (process3 occur)
Circumstance 2: more sodium chloride is added to the mixture? (process3 occur) due to common ion
Circumstance 3: more water is added to the mixture? (process 1occur)
Circumstance 4: more solid calcium chloride is added to the mixture? (process 2 occur) and solubility will not increase
