APFIVE Common Ion Effect on AgCl Solubility
A student studying the common ion effect adds NaCl to a saturated solution of AgCl and observes that the solubility of AgCl decreases. They conclude that the presence of Na+ ions is responsible for this effect. What is the correct explanation?
A
The Na+ ions increase the solubility of AgCl, not decrease it.
B
The decrease in solubility is due to an increase in the solution’s temperature.
C
The decrease in AgCl solubility is due to the common ion effect of Cl- ions, not Na+ ions.
D
The presence of Na+ ions has no effect on the solubility of AgCl.
