how come when you put sugar in soda it fizzes over?

you're forcing the CO2 out of solution all at once.  because it can only exit through a small opening it seems explosive

Salt occurs as (Na+Cl-) \nThe water molecules come between the atoms of salt , and thus breaks the ionic bonding b/w Na+ and Cl-.Na+ is attracted to the lone pair of oxygen atom of the water molecule and Cl-to the H atom of water molecule , thus hydrolysis and solvation of salt occurs, which makes the salt to dissolve fast whereas in sugars, the molecules are quite big and moreover sugar has a planar geometry , and contains bonds like -C-H, -C-OH-, -C-O-C-, these breaking of these bonds require more energy and moreover -C- is non-polar, thus increasing the no. of C atoms will make a compound to dissolve less in water. Sugar has 6 Carbon atoms.\nThus to dissolve sugar , we need stirring.

Hiccups are caused by trapped air. Carbonated drinks like soda contain alot of air trapped in bubles which gives it the fizz. Hence those bubbles get trapped and cause you to burb or hiccup.

The gas is turned into liquid by compressing it and well mixed up with water. When we shake the soda it turns back to gas and hence needs more room than it has.

Stuff with lots of sugar, especially sodas and other drinks.  Try just drinking water.

carbonated drinks [COKE] have co2 which  is the gas that cause the foam,bubbles when you pour it. I dont think it really burns but it gives you that sensation because when you BURRRRRP! {EXCUSE ME} the gas is rushing out escaping thru your nostril bring your inner body temperature to ambient tempeerature usally cooler that body temperature

I assume you mean the amount of sugar in a solution and not just a heap of sugar?\n\nyes, if the sugar concentration is too low, its not really interesting, if it is too high, then it gets too thick and ants get problems drinking it, and it may become more work than it's worth. \n\nYou can make a summer science project out of this if you ever want to:\nhttp://www.science-projects.com/SummerProjAnts.htm

Because if the composition is too acidic or too basic one way or the other, the soda could be toxic.\n\nAlso, it wouldn't taste good or sell well.

If it happens only when you drink the cola it is probably heartburn or gas, try drinking another cola.  You could also be having an allergic reaction to something in that particular soda.  I would stop drinking the soda.   If the problem continues without the soda you should contact your health care provider.

Only the water will evaporate. Everything else will remain. You'll be left with Kool-aid/sugar crystals\n\nP.S Kool-aid is not sugar, it's artificial flavors and colors. If it were sugar, why would you need to add sugar?

Actually, this can happen with any dense material, not just mentos.   Like the twisted tab of the can of coke...\n\nYou see, soda is a supersaturated solution of CO2 in water.  That means, there is way more CO2 in the water than there should be at the given surrounding temperature.  This is achieved by forcing the CO2 under high pressure.  Anyway, a supersaturated solution is unstable and is prone to destabilize with the acting of external forces... like a dense material sinking to the bottom of the solution.  This results in the eruption of excess CO2 into gaseous form.\n\nThis has worked for me a lot.   Take a standard 300 mL bottle of Coke.  Open the bottle, and quickly twist the bottle cap (to make it denser and to allow it to fit through the bottle neck), then plunge it into the bottle.  And , fooosh!!  You'll get your eruption.  Take note that you have to do all this quickly, because if you don't the gas in the bottle will escape pretty quick and the above phenomenon won't be observed.

Actually, the CO2 is not in liquid form.  The CO2 molecules are trapped in the liquid.  That is why you can actually see the CO2 rise to the top of the soda.\n\nWhen you shake the bottle, you are releasing a large volume of the CO2 molecules.  However, you might wonder why the pressure just stays the same since nothing has been added to the bottle.  What's the difference between the CO2 molecules being in the liquid or in the air space above it?  Quite a bit of difference.\n\nWhen the CO2 is in the liquid, it is not able to expand like  a gas.  It does take up space in the liquid, but the liquid keeps it in a more confined space.  When the CO2 escapes the liquid, it now fills the air space as a gas pushing in all directions.  It is now able to expand like a normal gas which is why you get more pressure.

This may sound dumb, but it really works!  Eat a tablespoon full of sugar.  Try to swallow it all at once and you will not have another hiccup afterwards.  Works from experience.  I am a cocktail waitress at a bar and when all the drunks get them I make them take a shot of sugar.

At a higher temperature, the water molecules are further apart, thus creating more space for the molecules of sugar.  Consider two identical bottles: (A) is filled with sand and (B) is filled with gravel.  If you pour water in each bottle, which one will take more water?  Obviously (B) because there is more space available.

try to dissolve more sugar in it, if it doesn't work it's saturated.\n\ntake a drop of it out and put it on a surface, within 10 mins the water will evaporate leaving a sugar crystal the same size and shape as the water droplet.\n\nNot to scientific but useful all the same.

Same reason a water bottle will crack(water expands when frozen), the only difference is the carbonated drinks aren't completely frozen so it leaks everywhere.

It is a reaction that will eventually dissipate.  The more times you make it make that taste, the faster it will go away.
