Sodium Chloride NaCl has an ionic bond. This type of bond is formed between a metal sodium, Na and a non-metal chlorine, Cl . In this bond, the metal loses one or more electrons to become a positively charged cation, while the non-metal gains one or more electrons to become a negatively charged anion. In the case of NaCl, sodium loses one electron to become Na+ and chlorine gains one electron to become Cl-.When NaCl is dissolved in water, it dissociates into its constituent ions, Na+ and Cl-. Water molecules, being polar, surround these ions and stabilize them in the solution. This process is called hydration. The positive end hydrogen atoms of water molecules is attracted to the negatively charged chloride ions, while the negative end oxygen atom of water molecules is attracted to the positively charged sodium ions. This interaction between water molecules and ions helps to separate and disperse the ions throughout the solution.As a result, the NaCl solution contains a high concentration of mobile ions, which can conduct electricity. This is why NaCl behaves as a strong electrolyte when dissolved in water. The presence of a large number of ions in the solution allows it to readily conduct an electric current, making it an excellent conductor of electricity.
