Question

When NaCl is dissolved in water, the sodium ion becomes:
A) oxidised
B) reduced
C) hydrolysed
D) hydrated

Answer 1

Hint: We know that, when any salt dissolves in aqueous solvent they break into ions forms one is cationic which has positive charge ion and another is anionic which has negative charge ion. The water molecules get dissociated in hydronium ion and hydroxide ion.

Complete Step by step answer: As we all know, when sodium chloride that is NaCl dissolves in the aqueous solution that is water, usually forms an ion they are the sodium and chloride. The polar water molecules show and are strongly attracted to each other by a famous interaction that is ion-dipole interactions. The solvent molecules that are water are generally surrounded by the ions which are removing them from the salt crystal and easily forming the solution. By means of the dissolving process, the individual ions which are removed from the solid crystal, get completely separate and form hydrated species in the solution.
The salt when dissolved in water forms an ionic compound. Let us consider the diagram of salt NaCl which is dissolved in water given to the ions as shown below.

Hence, we can conclude that when NaCl is dissolved in water, the sodium ion becomes hydrated.

Hence, the correct option for this question is D that is hydrated.

Note: The salt in a chemistry can be described by having an ionic form get-together with the cations and the anions. The salts get dissociated with the effect of temperature and changes in the solvent which is needed for dissolving.
