Introduction Of Project

Project is about gas and chemical reactions by discovering how to inflate a balloon using baking soda and vinegar.

Purpose of Project

The Purpose of the project is to demonstrate the power of gas produced when of baking soda and vinegar are mixed.

Why we chose this project? We chose this project because, The concept that are required to be understood

is very much familiar with us. We can use this project in our teaching. It is based upon the concepts that are present in

the Science Curriculum. It is achievable for us .

Research QuestionsWhat do you think will happen when baking soda and vinegar come in contact (what will be produced)?What do you think will happen to the balloon attached?What makes ballon to inflate?

Background Knowledge Vinegar is an Acidic Solution An acid is any substance that forms hydrogen ions (H+) in

water.(Arrhenius definition, the Brønsted-Lowry definition, and the Lewis definition)

Baking Soda is a Basic (non acidic) and chemical compound sodium bicarbonate.

A base is any substance that forms hydroxide ions (-OH) in water. (Arrhenius theory)

Other Researches Mr. M. Gonzalez in 2008 from Newyork (Aim =

What is PH)

Other Researches The nutritionist of the Lewiston School

District, United State ( Aim = Foods contain specific materials such as fats, proteins, sugars, and acid that work together to create healthy or unhealthy eating choices)

Material Balloon Small bottle Small funnel Baking soda (2 tablespoons ) Vinegar (8 tablespoons)

Experiment

Step 1 Carefully pour vinegar into the plastic

bottle

Step 2 Using paper funnel, pour baking soda into

the balloon. Try not to spill.

Step 3 With out spilling the baking soda, put

balloon on the bottle’s mouth piece.

Step 4 When ready, lift your balloon and let the baking

soda fall into the vinegar.

Answer of 1 & 2 Research question

What do you think will happen when baking soda and vinegar come in contact (what will be produced)?

What do you think will happen to the balloon attached?

Step 5 Shake baking soda into the bottle

Finding Watch in FIZZ & inflate the balloon

Result and Answer of 3 Question The reaction between baking soda (NaHCO3) and

vinegar (CH3COOH) is actually two reactions, an acid base reaction followed by a decomposition reaction.

Acid Base Reaction When the two ingredients are mixed, hydrogen

ions ( H+) from the vinegar react with the bicarbonate ions (HCO3- ) from the baking soda to form a new chemical called carbonic acid (H2CO3).

Decomposition Reaction The carbonic acid thus formed then immediately

decomposes into carbon dioxide gas (CO2) and water (H2O).

H2CO3 ---> H2O + CO2

It's this carbon dioxide gas that you see bubbling and foaming as soon as you mix baking soda and vinegar together.

Driving Questions

Have you ever wondered how a cake rises?

Do you know what ingredients in a cake that causes it to rise?

Conclusion Any baked goods that rise rely on carbon

dioxide bubbles to get the job done. You can make these bubbles either by using yeast or by using baking powder or baking soda.

Conclusion Baking powder is made by combining baking soda

with an acidic ingredient, such as tartaric acid or calcium acid phosphate.

Take a look at a recipe for quick bread. If the recipe includes baking soda but no baking powder, it will probably also include an ingredient that's acidic-such as buttermilk, sour milk, or orange juice.
