The shift in equilibrium position of a chemical reaction that occurs because of the addition of an ion already involved in its equilibrium reaction is called the_____.
A) complex ion equilibria
B) common ion effect
C) specific ion effect
D) Averch-Johnson effect
E) Quasi-perfect equilibrium

Question

The shift in equilibrium position of a chemical reaction that occurs because of the addition of an ion already involved in its equilibrium reaction is called the_____.​
A) complex ion equilibria
B) common ion effect
C) specific ion effect
D) Averch-Johnson effect
E) ​Quasi-perfect equilibrium

Quizplus · Accepted Answer

The common ion effect occurs when an ion already involved in an equilibrium reaction is added, causing a shift in the equilibrium position. This effect can be observed through Le Chatelier's principle and helps to explain the behavior of weak acids and bases. The other choices (A, C, D, and E) are not accurate descriptions of this phenomenon.
