the dissociation of a weak electrolyte is suppressed when\n○ a strong electrolyte with a common ion is added to the weak electrolyte solution.\n○ a strong salt is dissolved with the weak electrolyte solution.\n○ a strong electrolyte with a different ion than the weak electrolyte is added.\n○ the strong electrolyte solidifies in the presence of the weak electrolyte.
Answer
Answer:
A. a strong electrolyte with a common ion is added to the weak electrolyte solution.
Brief Explanations:
According to the common - ion effect, when a strong electrolyte with a common ion to a weak electrolyte is added to the weak - electrolyte solution, the dissociation of the weak electrolyte is suppressed. This is due to Le Chatelier's principle, which states that a system at equilibrium will shift to counteract an applied stress. Adding a common ion increases the concentration of an ion already present in the equilibrium of the weak - electrolyte dissociation, causing the equilibrium to shift towards the undissociated form of the weak electrolyte.
