Baking Soda And Vinegar Volcano Research Paper

We gathered up the last remaining bits of snow this afternoon to make a Baking Soda Volcano.

I placed a small glass jar in the centre, with the top level with the top of the snow.

How to make a snow volcano

What you need

2 spoonfuls of baking soda (bicarbonate of soda )

1 spoonful washing up liquid

a few drops of red food colouring

30 ml vinegar

Method

Add everything except the vinegar to the water bottle.

Stand back, get ready……add the vinegar and watch the eruption! If it doesn’t work so well, add a bit more washing up liquid and vinegar.

I loved how easy this was to make and how great the red looked against the snow!

 

 

What do you think of our Baking Soda Volcano?

The Science bit

Vinegar (an acid ) and bicarbonate of soda ( an alkali ) react together to neutralise each other. This reaction releases carbon dioxide, a gas which is the bubbles you see, these bubbles make the washing up liquid bubble up to give the reaction shown above.

You could also try making a multi-coloured snow volcano.

Answer 5:

Baking soda and vinegar react with one another because they both have a lot of energy that they don't want and they can help each other get rid of it! You might think this explanation is too simple, but it's true to what's happening.

Before we go into more detail, let's be clear about our materials. The chemical name for baking soda is sodium bicarbonate. Its chemical formula is NaHCO3, meaning it's made of one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms. Vinegar is a mixture of acetic acid and water. Dilute acetic acid is the chemical name for vinegar, and its chemical formula is CH3COOH. From here on out I will write the chemical formulas in parentheses.

Baking soda is a base, and vinegar is an acid. An acid is a chemical that wants to get rid of a proton, or a positively charged hydrogen atom. A base is a chemical that wants a proton. When you mix an acid with a base exciting things can happen because the acid is ready to give away its proton and the base is right there to receive it!

Water is often added to acids and bases to tone down the intensity of this exchange. Water also acts as host in which the acid and base can break apart and react. In water, baking soda breaks apart into a positively-charged sodium ion (Na+) and a negatively charged bicarbonate ion (HCO3-). An ion is a charged atom or molecule. Acetic acid doesn't break apart on its own in water as much as sodium bicarbonate; it's mostly diluted so it's not as strong.

When we mix baking soda and acetic acid in water together, acetic acid gives its proton to the broken-apart baking soda and together they form sodium acetate (CH3COONa), water (H2O), and carbon dioxide (CO2). These products are created quickly, and the carbon dioxide comes out as a gas, so the whole event is spectacular as you've seen!

By reacting with each other, the acidic acetic acid and the basic sodium bicarbonate give up a lot of their energy and create things that have a lower energy relative to each other. The universe favors things at their lowest energy, and so we see a lot of exciting reactions involving acids and bases.
