* Electrolytes: Baking soda is a salt, and salts are electrolytes. When dissolved in water, they dissociate into ions (charged particles).
* Ions and Conductivity: Ions are the carriers of electric current. The presence of free ions in the solution allows electricity to flow through it.
Here's a simple explanation:
1. Dissolving: When you dissolve baking soda in water, the sodium bicarbonate molecules break apart into sodium ions (Na+) and bicarbonate ions (HCO3-).
2. Charge Carriers: These ions are now free to move around in the solution.
3. Conductivity: If you apply a voltage across the solution, these ions will flow towards the oppositely charged electrodes, carrying the electric current.
Important Note: The conductivity of a baking soda solution depends on its concentration. A higher concentration of baking soda will result in more ions and therefore better conductivity.
