Question

Demonstrtate electrolysis of water

Answer 1

Hello!!!

Hey my dear friend here is your answer________

♦♦♦ Energy is stored in the bonds of molecules. When these bonds split apart, the energy released can be used to do work.


♦♦♦ Breaking apart liquid water molecules into hydrogen and oxygen gas creates an enormous amount of energy, which can be turned into useful electricity to power our homes and cars.


♦♦♦ To break these bonds, some amount of energy is required to get the atoms in water molecules active enough to break apart from each other. At home, we can supply this energy with a battery.


♦♦♦ All batteries have two terminals, or ends: a positive terminal and a negative terminal.


♦♦♦ The water then connects these terminals, so energy can flow between them. As the electricity passes through the water, it splits the water!

$\tt \red { \pmb{\: \underline{To \: Demonstrate \: The \: Electrolysis \: of \: Water}}} : -$

$\bf \: { \pmb{ \colorbox{lavender}{ \blue{Material \: Required}}}} : -$

• One Battery of 9V
• Two Graphite Pencils
• One Beaker
• Tap Water
• Connecting Wires and tape

$\bf \: { \pmb{ \colorbox{lavender}{ \blue{Procedure }}}} : -$

• Sharpen both ends of both the pencils.
• Fill the beaker with tap water. Make sure that the contact with the Graphite in the pencils is perfect
• Secure the wires with tape.
• Use a piece of Cardboard to hold the pencils in a vertical position.
• Place the exposed tips of the pencils in the water,such that tips are fully submerged but aren't touching the bottom.
• The pencil is being used as ELECTRODE here. Now, Wait for 3-4 minutes and observe carefully.

$\bf \: { \pmb{ \colorbox{lavender}{ \blue{Observation }}}} : -$

• Small Gas Bubbles will formed near the electrodes.
• The change takes place in the tap water is the Chemical Change.
