Answer 1

Answer:

d. Salts undergoes a chemical reaction with the particles of the solution and increase its conductivity

Explanation:

Salt compounds like potassium chloride (KCl) and sodium chloride (NaCl) mentioned in this question have the ability to disintegrate into their respective ions or charged atoms when dissolved in water. For example;

NaCl (aq) → Na+ + Cl-

However, these ions (Na+ and Cl-) are responsible for the ELECTRICAL CONDUCTIVITY of a solution. Hence, a salt compound when placed in an aqueous solution will form ions, which will conduct electricity. Hence, salinity of a solution increases its conductivity.

According to this question, salts undergoes a chemical reaction to with the particles of the solution to form ions that increase its conductivity.
