The \"common ion effect\" addresses the solubility of sparingly soluble ionic sa

Question

The "common ion effect" addresses the solubility of sparingly soluble ionic salts in polar solvents. Which of the following statements encapsulates the "common ion effect"? a. Polar solvents dissolve polar solutes. Likewise, nonpolar solvents dissolve nonpolar solutes. b. A salt will be more soluble if one of its constituent ions is already present in solution. c. In a polar solvent, salts with the same anion will have similar solubilities. d. A salt will be less soluble if one of its constituent ions is already present in solution. e. Increasing the ionic strength of the solution increases the solubility of salts in the solution.

Explanation / Answer

1) answer will be (c)

As adding a common ion decreases solubility, as the reaction shifts toward the left to suppress the stress of the excess product ( the ions produced by the salt with common ion)

2) The answer will be (a)

We know that Ion-selective electrodes are used for detection of specific ions in a mixture of ions. indicator electrode—responds to the analyte’s activity,
