Why does salt dissolve faster than sugar?

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.

Anything that dissociates well in water. Any strong acids or bases are good, so are salts of those since they exists as ions in solutions. Weak acids and bases are weak electrolytes, since they don't dissociate as well. The most common is probably table salt, NaCl. Potassium by itself is just a metal the reacts violently with water and is not a good electrolyte, but potassium compounds are, as are sodium compounds. \n\nNote: Remember, just because something dissolves well doesn't mean that it is necessarily a strong electrolyte., it must also dissociate into ions. Sugar dissolves in water, but since it doesn't separate into ions it is not an electrolyte.

gases are in general more soluble in cold liquids, so less of the dissolved carbon dioxide is lost from an iced glass of Coke vs. one at room temperature.  I've also noticed that drinks with artifical sweeteners tend to go flat faster, but I have not figured out yet whey it seems like the presence of large amounts of sugars affect the solubility of the CO2 yet.

Common table salt has other ingredients in it including sugar. It is not close to pure.   It would take very efficient purification.

If by 'undissolved' you mean why are some salts insoluble in water, then I think we are in business.\n\nIn order for a salt to be soluble it has to be energetically favorable for the ions to separate. This requires a negative gibbs free energy. G = H - TS So you have to find the H and S values for the solid to aqueous solution and see if G will be negative for a given temperature.\n\nA method I recently learned to make insolube salts more soluble is to add other ions to the water...but you have to be careful to not add a common ion...or Le Chantliear will come into play.

I'll take a stab at this one.  \n\nIf you're comparing the two, water will disolve more NaCl than it will Sodium bicarbonate because it dissociates a lot faster and effienciently (due to its electronegativitiy and other factors).  \n\nOn that same note, if you are asking directly if both dissolve faster in cold or hot water, hot water is always your best bet with solids dissolving in water.  On another note, if you want to disolve a gas in water lower temperatures are pretty much the only way to accomplish this (but thats a different topic).  \n\nSo in short, both will disolve better in hot water!\n\nCheck out the source below it is very helpful.  Oh and by the way, Sodium bicarbonate does dissolve in water.

a. sugar dissolves into water and the sand can then be filtered out.\n\nb. can be distilled\n\ni'd have to look up the rest. post them when you find them, I'd like to know!

salt is a mineral that is required by the body, but excessive amounts may cause high blood pressure in some people.  Not in all people, just some people.    But to be safe, you should use it sparingly.\n\nsugar, if you are talking about refined sugar is empty calories and is only used to make things taste sweeter.  It is a carbohydrate which our body already gets enough of in our regular diet, but there are healthier sugars than others.   Fructose which is sugar found in fruit and Lactose which is found in dairy products.   These sugars are metabolized differently than refined sugar and are good sources of energy.  good luck

Your cells are always in an isotonic solution which means the solute level (salt and other material) and the water level is about the same. Salt water is a hypertonic solution because the levels of solute outnumber the water. When you drink salt water it causes the water in your cells to leave the try to reach equilibrium. This causes them to shrink and ultimatily make the organism die.

If you make them the same concentration (say 1 molar of each) the salt water will have a lower freezing point, and so will need to be colder before it freezes.  Freezing point is affected by the concentration of particles dissolved in the solution.  Since salt forms two ions and sugar forms only single molecules, you have more particles in a salt water solution than you do in a sugar water solution.

Excellent question.  Food for thought for both of us.  Let's see- changing the pH of water could allow for greater or less solubility of minerals.  With more minerals in solution, the rate of evaporation increases while the boiling/freezing point lowers, as intermolecular attraction is decreased.  The opposite would then be true with less minerals in solution.

Your friend is very true. He has just been explaining the solubility of citric acid in water. Citric acid is indeed polyprotic, in simple terms, it can release 3 H+ ions into solution. Also, to add to what ur friend has said, Citric acid can form Hydrogen bonds faster and easier compared to NaCl. Hydrogen bonds are formed between an electronegative atom of one molecule and a Hydrogen atom of another molecule (Intermolecular) OR an an electronegative atom of one molecule and the Hydrogen of the same molecule. In the case of citric acid, it is Intermolecular Hydrogen Bonding between citric acid and water. \nThis makes citric acid to dissolve better in water than NaCl.

Baking soda (sodium bicarbonate) dissolves faster.  Flour doesn't dissolve, it's a suspension.

good obervation!\n\nwell the reason is that when anything dissolves in something, that anything has it molecular bonds broken and interrupted by the solvent molecules. now to break the bonds of the solute(which dissolves) we need energy. this energy is provided by the solvent molecules. \n\nnow when anything is hot it has more energy associated with its molecules. hence hot milk has more energy too. so.....when it has more energy itself, it can provide the sugar molecules with more energy, hence its bonds can be broken faster, hence it dissolves faster.\n\nhope ur satisfied.

warm water dissolves ice faster than warm air because it can transfer and absorb heat faster than warm air of the same temperature

The hotter it is, the faster I think it will desolve. Hot liquids are moving at a faster rate, so the water molecules would be "bummping" into the aspirin more. This would cause it to disolve faster. Also, the hotter the liquid, the faster other things like sugar disolve.

Salt only helps the boiling point rise a little. It will boil more rapidly. It will not decrease time it takes to reach boiling point.
