Why Does Diet Soda Float?
Diet sodas and soft drinks usually contain carbon dioxide gas under pressure. This is what makes them fizzy. But if you shake a can of regular soda, it goes flat – the bubbles disappear – because the gas comes out of solution and forms tiny bubbles that float to the top.
The simple version:
If you take a can of regular soda and put it in your fridge for a couple of hours, then open it, the liquid will be mostly gone with just an inch or so left at the bottom.
Why? Because as those super-cold temperatures lower, carbon dioxide enters those bubbles more slowly, which causes those bubbles to become more extensive as they rise towards the top (in other words: they become less dense).
By shaking a soda before opening it, you make sure that the gas is evenly distributed throughout, so when you crack open the can, all of that pressure comes out at once.
As for diet soda, you were shaking them isn’t likely to do much. This is because the carbon dioxide in the drink is already more or less uniformly dispersed throughout (while some molecules are dissolved into your glass while others are floating around as bubbles). That means there’s nothing to shake up.
What will happen if you put a shaken regular soda in your fridge is pretty cool: The remaining liquid will become more concentrated with sugar over time and form a little syrup on top.
How does CO2 get into soda?
The process starts with sugar beets or sugarcane. Sugar beets are white, with a thin skin that contains the sugar beet juice. Like potatoes and tomatoes, they grow in the ground and get pulled up when it’s time to harvest them.
The outer skin of the sugar beet protects its precious juice from being exposed to too much light while it sits on the truck on the way to the processing plant — sunlight can destroy some of the chemicals we use to make soda pop.
Once you get your sugar beet into the factory, you scrub off that layer of skin and then slice them into little strips (called cassettes they), so they’ll fit through a machine where they’re shredded, washed in hot water, and pressed flat like Play-Doh between two metal plates covered in tiny holes.
That squeezes out all of the sugar beet juice, which is then sent over to another machine that spins it all around, mixing in lots of hot water and chemicals (like phosphoric acid, calcium hydroxide, and de-ionized ash).
The resulting liquid looks disgusting
— because it contains a bunch of sugar infused with grapefruit juice concentrate and caramel coloring — but don’t worry: what you’ve just made is molasses! And now the fun part happens – your molasses gets heated up until bubbles start to fizz everywhere. When the syrup boils, water evaporates into steam, making room for more sugar syrup to take its place.
Eventually, this chamber fills up with sweet fog that smells quite strong, but get used to it because this is what will become your soda pop. The last step is to mix the molasses with the calcium hydroxide (also known as lime or pickling lime), which causes calcium carbonate to drop out of the solution and solidify in little nuggets around the molasses. We call these “kolok-ettes” (no relation to Koloktos from Skyward Sword).
What is the density of coke:
density is defined as mass per unit volume. The density of coke in kg/m^3 = it’s mass(in kilograms) divided by its volume (in m^3). Density of coke = 8600kg/m^3. but it can be calculated with the following formula too; for this, you need to know that 1m cube of water weighs 1000Kg than coke.
Density(kg / m³) = object weight divided by 100 less than the object Volume in cubic meters.
Density=8600kg/100cm^3 = 8600×0.01=860600 kg / m³ or Kg/l .
Does sugar float in water:
No, sugar does not float in water. Sugar sinks to the bottom of water because it is denser than water. The density of sugar is 1020kg/m³, and the density of water is 1000 kg/m^3. The sugar and water densities ratio is greater than 1, so the sugar sinks in the water. However, boiled potato (a low amount of starch) floats on top of the boiling water because its density is lower than pure water. (The potato’s density is 998kg/m^3).
How much does a gallon jug contain:
A gallon jug can hold 128 fluid ounces if it’s packed to the top with no air space at the top.
How many moles are in 1 gr of calcium carbonate:
1 gr of calcium carbonate has a mass of 100.08 grams and therefore has a molar mass of 100.08g/mole, which is 50.002222 molecules per mole or 0.5 mol CaCO3 if you prefer to use that way for the calculation.
Calcium carbonate does not fully dissociate, so it doesn’t matter whether you define it as 0.5 mol or 50 g/mol since the answer will always be 8623 ppm (X) by weight.
Since this compound is an ionic solid, it can also contain X molecules (or ions) per cm cubed. So to convert from ppm (weight) to molecules/cm cubed, multiply X by the molar mass of calcium carbonate divided by the molecular weight of CaCO3.
