It is possible to make sodium Hydroxide chemically.
The same compound, NaOH, is comprised of 3 single atoms and is referred to as sodium hydroxide, caustic soda, and lye.NaOH can be used in high schools to teach about pH.You can use some simple supplies to make your own NaOH in the lab or impress your students.This article shows how to make a small amount of NaOH without electricity.
Step 1: The materials should be placed on a clean surface.
It is important to clean and dry your work area before starting the experiment.Make sure you only use batteries for this kind of experiment.You are going to demonstrate a reaction.When a current passes through salty water, it creates bonds between the water and the salt.Lead acid batteries are not charged while conducting this experiment.
Step 2: Salt is dissolved in 1.24 cups of water.
Salt can be poured into the water by adding it to a glass.When the salt is completely dissolved, stir it in with a spoon.Attach the lid to your cup and shake it up and down to mix the salt in.Make sure the salt is completely dissolved.
Step 3: The top and bottom of the pencils are covered in lead.
Carefully remove the top of the wood using a knife.If you want to avoid harming yourself, hold each pencil from the bottom.The led will be placed in the salt-water solution.The wood on the eraser ends will connect to the battery terminals via copper wire.Don't cut the pencils in the direction of a body part.
Step 4: The pencil lead can be inserted through a piece of cardboard.
To make it easier to insert your pencils, poke 2 holes through a piece of cardboard or stiff paper with a toothpick.After that, press each piece of lead through the paper or cardboard.There should be wood underneath the exposed lead after pushing the ends through the cardboard or paper.
Step 5: The cardboard has the lead in the water.
The exposed lead tips should be submerged if the cardboard is balanced over the opening in the cup.The paper needs to cover as little of the glass as possible.If all of the glass is covered with a piece of paper or cardboard, use scissors to remove it.
Step 6: Attach the pencil lead to the battery terminals.
Wrap wire around the pencil leads.One should connect to the positive terminal and the other the negative terminal.The wire should be tightly bound.Each pencil should have one end of exposed lead inserted through cardboard or paper and the other attached to the battery via copper wire.Don't cross uncovered sections of the lead.Make sure you are in a well-ventilated area because hydrogen and the oxygen can burn and explode with any little spark and chlorine can be toxic.If you accidentally start an electrical fire, smother it with a dry blanket or fire extinguisher.Don't pour water on it because it can shock you.
Step 7: Wait until no more bubbles form.
There will be bubbles in the 2 wires.Oxygen, chlorine, and hydrogen will be present in the positive one while the negative one has hydrogen.As the bubbles leave, more and more NaOH is formed.Don't touch the wires while the battery is on.
Step 8: Remove wires from the apparatus.
Pull out the pencils from the piece of cardboard or paper that was in the cup after you disconnected the copper wires.Clean up any water by putting everything on a dry towel.Don't touch the pencils that were submerged in the NaOH because they can burn your skin.
Step 9: You can boil the solution you made in the dish.
This step should be done in a professional laboratory at a college, university, or workplace.Do not attempt this step if you don't have access to one.Place the solution on the boiler.The water will separate from the NaOH if it is boiled at a temperature of 100 C.Under a hood be sure to boil it.The dish will melt if you use aluminum to boil it.In a kitchen, outdoors, or in a non-chemically designed area, never boil your solution.While handling the solution, use chemical gloves.If NaOH contacts your skin, it can cause severe chemical burns.
Step 10: Put the NaOH solution in a container.
Purchase a new chemical container with a funnel that is rated for NaOH.Slowly pour the cold NaOH into the container.To get rid of extra gloves, be sure to use a lab-supplied waste container.Remember that you can burn yourself if you use caution.This is very dangerous since you now have a solution that is over 50% NaOH.
Step 11: You should transport and store your NaOH with care.
As you transport the NaOH, this is the riskiest step.The trolley can be used for more stability.When moving around corners, walk slowly.Once you reach the storage site, place the NaOH container in a larger, waterproof, and chemically rated container.Make sure that it is clearly marked.
