Question

What will happen if we drop a battery in salty water and put two test tubes filled with water on it where the bubbles are being formed from both ends of battery.. PLEASE HELP ME FAST AND I WANT CORRECT ANSWER.. THANKS

Answer 1

Electrolysis is a process of using electricity to create a chemical reaction. Here we are splitting water molecules into their individual components: Hydrogen and Oxygen.
Since water is a relatively poor conductor of electricity ,and we are using a small volt battery, we need to add something to the water to improve its ability to pass electricity: such as salt ( sodium chloride Nacl) .Salt is composed of 2 atoms: Sodium and Chloride. In this process, electricity flows down the graphite pencil leads and flows through the water/salt solution.


• Oxygen molecules form as bubbles on the positive (+) terminal. They immediately combine with chloride molecules from the salt and the bubbles become chlorine gas – Chlorine is household bleach!

• Hydrogen molecules form as bubbles on the negative (-) terminal.
