Read the following statements carefully and select the correct option.
Assertion [A] : Salt solution is a good conductor of electricity
Reasoning [R] : Salt dissociates into ions when dissolved in water

Correct option is A

The correct option is (a) Both (A) and (R) are true and (R) is the correct explanation of (A).
Assertion (A): Salt solution is a good conductor of electricity
This statement is true. When a salt dissolves in water, it dissociates into its constituent ions, which are positively charged cations and negatively charged anions. These ions are free to move around in the solution and carry an electric charge. When an electric field is applied to the solution, the ions will move in the direction of the field, creating an electric current. This is why salt solutions are good conductors of electricity.
Reasoning (R): Salt dissociates into ions when dissolved in water
This statement is also true. When a salt dissolves in water, it breaks down into its constituent ions. For example, when sodium chloride (NaCl) dissolves in water, it dissociates into sodium ions (Na+) and chloride ions (Cl-). These ions are free to move around in the solution.
