5. In this experiment, several solvents will be available to you to determine the common iorn effect on solubility as well as the effect of dissolving in a solvent without any common ions. The solvents available are the following: water, 1 M NaNO,, 2 M NaNO,, 1 M KCI, 2 M KCI, 1 M NaCI, and 2 M NaCI. a. From the solvents available to you, choose four that can be used to accomplish the objective of investigating common ion effect. Water should be one of the solvents to use. (Note that it may be necessary to change these solvents you've chosen after answering the questions ahead.) i. Water iv. b. Which two solvents can be used to make a conclusion on how the solubility of KNO, is affected by the following scenarios? Only a total of four solvents should be used below. the presence of a common ion in the solvent and e the use as solvent of an ionic aqueous solution that does not have any common ions and the change in concentration of a common ion present in the solvent and c. Do you need to make any changes to your initial four solvents proposed in (a)? If so, list your revised choice of four solvents below. i. Water iv.

Explanation / Answer

The suppression of dissociation of a weak electrolyte in the presence of a strong electrolyte having a common ion is called common ion effect.

a)To effect the common ion effect, the solvents should have ions in common. So the other 3 solvents can be, NaNO3, 1 M NaCl and 2 M NaCl which Na+ ion in common

b)
