Which term refers to the process by which ions that have entered solution are kept in solution?
2 answers:
Answer : The correct option is, hydration
Explanation :
Hydration : It is a process in which the ion or substance combines with water and kept in the solution. In the hydration process the solvent is water molecule.
For example : When the sodium chloride is dissolved in the water then the positive sodium ion get surrounded by the water molecule through their oxygen ends and the negative chloride ion get surrounded by the water molecule through their hydrogen ends.
Dissociation : It is a process in which the compound splits or dissociates into to two or more smaller ions, atoms or particles.
Electrolyte : it is a process in which the a molecule is completely dissociates into their respective ions in the aqueous solution.
Ionization : It is a process in which a molecule acquire a positive or negative charged by the gaining or losing electrons.
Hence, the correct option is, hydration.

Explanation:
Hello there!
In this case, since the buffer is not given, we assume it is based off ammonia, it means the ammonia-ammonium buffer, whereas the ammonia is the weak base and the ammonium ion stands for the conjugate acid. In such a way, when adding HI to the solution, the base of the buffer, NH3, reacts with the former to promote the following chemical reaction:
Because the HI is totally ionized in solution so the iodide ion becomes an spectator one.
