False

When salt (such as sodium chloride) is dissolved in distilled water, it dissociates into its constituent ions (Na+ and Cl-). These ions are charged particles that are free to move within the solution. As a result, the solution becomes conductive and can carry an electric current.

Explanation:

1. Dissociation of salt:
- When salt is dissolved in water, the water molecules surround the individual ions of the salt and pull them apart, breaking the ionic bond between them.
- In the case of sodium chloride (NaCl), it dissociates into sodium ions (Na+) and chloride ions (Cl-).
- The dissociation process can be represented by the following equation: NaCl(s) → Na+(aq) + Cl-(aq)

2. Conductivity of the solution:
- The ability of a solution to conduct electricity depends on the presence of charged particles (ions) that can move freely within the solution.
- In the case of the salt solution, the sodium ions (Na+) and chloride ions (Cl-) are free to move and carry electric charge.
- When an electric potential is applied across the solution, the positive sodium ions move towards the negative electrode (cathode), while the negative chloride ions move towards the positive electrode (anode).
- This movement of ions constitutes an electric current, indicating that the solution is conductive.

3. Distilled water vs. tap water:
- In distilled water, there are only a few impurities or dissolved substances present, so it is a poor conductor of electricity.
- However, when salt is added to distilled water, it significantly increases the concentration of ions in the solution, making it conductive.
- In contrast, tap water often contains various dissolved minerals and ions, which can contribute to its conductivity even without the addition of salt.

Summary:
- When salt is dissolved in distilled water, the resulting solution becomes conductive because the salt dissociates into charged ions that can move freely within the solution. This ability to carry an electric current contradicts the statement that salt dissolved in distilled water does not conduct electricity.
