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)
Healthy
Should be healthy to a certain extent, so as to not cause any physical discomfort
Cold
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
Refreshing
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
Hypothesis
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
Google
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

03
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
Material
Flavoured Water (Cold)
Beaker and collecting can
Stand
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
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:
Taste
With the use of Opitical Sensors
2. Testing
