Everything You'll Have Covered

Which solutions conducted electricity and caused the light bulb to glow? Why?

~ The salt water, water with lemon (acid-water), and water with soap (base-water) solutions caused the light bulb to glow. Salt crystals are ionized when dissolved in water. Ions transmit electrical currents because they are positively and negatively charged particles. The same is true for water solutions with lemon (acid) and with soap (base).

What is the difference between electrolyte and nonelectrolyte solutions?

~ Electrolyte solutions are solutions that are ionized when dissolved. They are composed of ionic compounds, such as salt water, water with lemon (acid), and water with soap (base). Nonelectrolyte solutions maintain their molecular structure when dissolved and do not conduct electricity. Examples include water with sugar and water with alcohol.
