Chemical Reactions And Equations Grade 10: Magic Balloon

Alright guys,


Manushree of Grade 10 has submitted another experiment.

Let's see what happens!

This experiment

For this experiment you will need approximately,

- 1 Tablespoon of Baking Soda (Sodium Bicarbonate)

- 1 Spoon of citric Acid

- 1 Balloon

- Some water


Step 1:- Take a tall, thin beaker (preferably glass)

Step 2:- Add a spoonful of baking soda to the beaker

Step 3:- Add a spoonful of citric acid powder into the beaker

Step 4:- Add about 20mL of water into the jar and immediately tie the balloon on top

The balloon should magically blow up

Let's analyse what exactly happened!

Ok so let's discuss what happened.

In this experiment, Manushree uses citric acid (An Acid) and Baking Soda ( A Base) mixed into some water.

Now, acids and bases are famous for readily reacting with each other when they come into contact with each other.

This case is no different, the moment citric acid comes into contact with baking soda, they react to form gas which in turn blows up the balloon.

Let's analyse the reaction that takes place

Citric Acid is chemically known as:- C6H8O7

Baking Soda is chemically known as:- NaHCO3

They react together in this form,

C6H8O7 + NaHCO3 ====> Na3C6H5O7 + CO2 + H2O (Water)

Now in this equation we see that Carbon Dioxide (CO2) is released, and this is ,in fact, the gas that fills the balloon up.


This type of reaction is commonly known as a neutralisation reaction.

Ok, enough talk, let's take a look at some pictures!

Again, Big Thank You to manushree of Grade 10 of JHCS Kondapur for submitting me this experiment.
