Perfect carbonated drink

Imperfect Perfection

What is a perfect carbonated drink?

Slightly Sweet

A slightly sweet aftertaste evokes a pleasant experience (for most of us)


Should be healthy to a certain extent, so as to not cause any physical discomfort


Cold drinks will have more carbon dioxide in it, which maintains the fizziness

Lemon or Orange flavor (or mystery)

Additional flavourings to all our taste lovers


Yup, goes without saying; drinks should be fresh and refreshing!

Mid Fizzy

Not too fizzy nor too little, hence we defined it as "mid" fizziness


If, in the given location for the production of a perfect carbonated drink, low temperature is present, pressurized C02 is applied to the water, and slight sweetness and naturally refreshing lemon and orange flavors are applied, a perfect carbonated drink is made!

Finding a suitable experiment to test our hypothesis


We researched how we could make C02 in a lab, without the use of burning or any other ways to generate CO2 that would produce harmful chemicals




Took notes from the video

We recorded all the needed materials and steps,

Picked an experiment

We then picked an experiment featured on Youtube

The experiment


Flavoured Water (Cold)

Beaker and collecting can


Round Flask

Marble (Calcium Carbonate) *

Thistle Funnel

Delivery Tube

Opitical Sensor

Diluted HCl *

Beehive Shelf

* for the production of CO2

Step 1:
Set up the experiment as shown on the right

Step 2:
Pour Dilute Hydrochloric acid into the round flask through the thistle funnel
The marble reacts with the acid and effervescent takes place, releasing CO2

Step 3:
Wait for the gas to go through the delivery tube into the collecting can

The equation is as follows:

CaC03(s) + 2HCl(aq) = CaCl2(aq) + H20(l) + CO2(g)

1. Production

Step 1:
Place the optical sensor next to the container with the carbonated water

Step 2:
Wait till the optical sensor processing gets finished

Step 3:
If the reading shows 6 - 8 g per liter of CO2, then it is of appropriate value

Step 4:

With the use of Opitical Sensors

2. Testing
