Why is citric acid more soluble in water than NaCl?

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.

Citric Acid is a compound. It is made up of more than one element. Only those more than 100 substances in the periodic table are elements. Any substance made up of two or more different kinds of these is a compound.

Citric acid is a weak acid, while sodium hydroxide is a strong base. The sodium would fall off the hydroxide (because it's strong), so the reaction would be:\n\nHC6H7O7 + OH- --> H2O + C6H7O7

Is this a chemistry question?  Generally speaking, you can increase the solubility of an acid by increasing the pH of the solution (adding a base).  It is also highly soluble in organic solvents given that benzene ring it's got.  Adding some alcohol to the solution should help.  The Merck Index (I've got a really old Tenth Edition) adds, "[solubility] in water increased by sodium phosphate, borax, alkali acetates or citrates."\n\nDepending on what you're doing, you probably only want to do one or the other (i.e., add a base or add an alcohol--don't do both).  General rule in experimentation: don't complicate things if you don't have to--the fewer variables the better.

because it has NaCl in it

Triglycerides are made up of a hydrophilic (polar) "head" group and three hydrophobic "tail" groups. Polar molecules dissolve well in water while polar ones do not. In water, triglycerides form micelles, with the water-loving parts facing the water, and the polar part buried on the inside.\n\nWhen you hydrolyse these molecules, you get three long carboxylic acids and a molecule of glycerol. I think both of these are soluble.

I will assume that "salt" is referring to sodium chloride, NaCl.  The solubility of NaCl increases with increasing temperature and decreases with decreasing temperature.\n\nSince you are starting with a saturated solution (meaning that it contains the MAXIMUM amount of NaCl at that temperature) and you are cooling the solution to 20oC from 60oC, the cooler solution will not be able to keep the NaCl dissolved and you will observe small crystals of NaCl precipitating from the solution.

This is a poorly worded question.  All chemicals have some solubility in water, however minute.\n\nOf these selections, I would go with A\n\nAdding a charge facilitates dissolution.\nMany covalent materials (oil) have low solubility \nMany large molecules are water soluble (Poly Ethylene Glycol)

Because water (H2O) is a polar substance... meaning that the molecules are balanced... positives and negatives.\nOil, on the other hand, is a non-polar substance.\n\nIf you follow the theory of "like dissolves like", a non-polar solute (oil) would NOT dissolve in a polar solvent (H2O).\n\nSo... they don't dissolve in each other... they just kind of sit on top of each other.\n\nI hope that made sense!

NaCl, the bonding is stronger

Salt or Sodium Chloride is highly soluble in water.  Salt is naturally occurring and large bodies of water that cover vast numbers of square kilometers come in contact with salt.  Over time it dissolves causing the water to be high in TDS or total dissolved solids such as NA CL.  When the water from oceans evaporates, the salt drops out of solution which increase the salinity of the remaining water.   The evaporated water returns to earth as fresh water which flows back into the oceans and the cycle continues.   Large Salt caverns are ancient spaces that have not been exposed to water for millions of years.

it's an organic acid\n\nhttp://en.wikipedia.org/wiki/Citric_acid

We've to get this clear first. Water is a polar solvent, gasoline is a non-polar solvent. By the principal of like-dissolves-like, polar molecules will dissolve in water, for example, NaCl; while non-polar molecules will dissolve in gasoline, for example, fats, phosholipids, alkanes, alkenes etc.\n\nFor the question you've asked,\nChloroform is a polar compund because Cl draws electrons from the carbon center and making Cl atoms have a higher concerntration of electrons. Hydrogen atoms in water carry a partially positive charge and hence are attracted to Cl molecule. Hence it is soluble in water.\n\nNa2SO4 is soluble in water. This is because it is actually 2 Na+ ions attached to SO4(2-) ions. Na+ ions get attracted to oxygen atoms in water which has a partially negative charge and SO4(2-) ions gets attracted to hydrogen atoms in water which has a partially positive charge.\n\nKCL is soluble in water because Cl atoms draws electrons from K. Follow the same reasoning as chloroform.\n\nFor BaSO4, it is insoluble in water. Only barium nitrate dissolves in water. Other barium salts do not.\n\nHope this helps! =)

lemon acid is also known as citric acid.\nlemons are 5% citric acid and the molecular formula for citric acid is C6H8O7\nacids are solutions that dissolve in water and that give water a pH of less than 7 (7 is neutral) when acids dissolve in water they give off H+ ions\n\nWhen acids are dissolved in water the water acts as a base and accepts the H+ ions to become H30\n\nread more about acids in a chemistry text book or at \nhttp://en.wikipedia.org/wiki/Acids

wow, well put mrjeffy! I have one thing to add though. Because all acids and bases are electrolytes, you can use pH to determine what is and isn't an electrolyte in a solution. If it come out as acidic or basic, it is and electrolyte(the darker, the more basic or acidic). If it comes out neutral, like Distilled Water, it is not. Also don't forget that non-electrolytes will not completely dissolve into solution in water.

Heat the solvent, then it can take more solute into solution than when it's cool.  Then when you cool it, it is supersaturated.

O2 is the least soluble in water, followed by Br2.\n\nthe problem is that both LiCl and methanol dissolve completely in water. LiCl since it is an ionic compound, and methanol since it forms hydrogen bonding with water. Therefore any order for LiCl and methanol would be correct I presume.
