Solution

The correct option is B

Dissociation


Step1 :Explanation for correct option

Dissociation : The ions that are already present in the solid component separate out when an ionic compound is dissolved in water.

This process is known as dissociation.

So correct option is b

Step 2 : Explanation for incorrect option

(a) Ionisation : Ionization is the process by which an atom or molecule gains or loses electrons, resulting in a negative or positive charge, frequently in conjunction with other chemical changes.

(c ) Separation: We've all seen our parents and grandparents separate small stones or pebbles from rice grains, lentils, filter tea leaves before ingestion, and a variety of other tasks. Separation of pharmaceuticals is commonly used to remove or separate particular compounds from their mixes.

(d) Electrolysis: The process of dissolving ionic compounds into their constituent components by delivering a direct electric current through the complex in a fluid form is known as electrolysis. At the cathode, cations are reduced, whereas anions are oxidized. An electrolyte, electrodes, and some type of external power source are necessary for conducting electrolysis.
