Perfect carbonated drink

Imperfect Perfection

What is a perfect carbonated drink?

Mid Fizzy

Cold

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

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

Slightly Sweet

Lemon or Orange flavor (or mystery)

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

Additional flavourings to all our taste lovers

Healthy

Refreshing

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

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

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

Picked an experiment

We then picked an experiment featured on Youtube

02

01

03

Took notes from the video

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

We recorded all the needed materials and steps,

The experiment

Material

Marble (Calcium Carbonate) *

Flavoured Water (Cold)

Stand

Diluted HCl *

Thistle Funnel

Round Flask

Delivery Tube

Beehive Shelf

Beaker and collecting can

Opitical Sensor

* for the production of CO2

1. Production

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)

2. Testing

With the use of Opitical Sensors

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: Taste
