Why is the sodium salt of acetylsalicylic more soluble in water than aspirin?
Wiki User
∙ 11y ago
Aspirin is the trade name for acetylsalicylic acid. In a solution of sodium hydroxide the acid will be convereted to its sodium salt which is soluble. It could be recovered from the solution by adding acid to neutralise the sodium hydroxide and regenerate the free acid form which would again be mostly insoluble. In plain water the aspirin is unchanged and remains largely insoluble, only 1g dissolves in 100g of water at 37'C.

∙ 11y agoSodium acetylsalicylic acid is more soluble in water than acetylsalicylic acid because it dissociates into ions (Na+ and the acetylsalicylate anion) which then attract water molecules to form solvation sheaths around them. Source: Heinemann Chemistry 2

∙ 12y agoif you look up the sturcutre of aspirin it consits of aromatic rings which are really stable and not very acidic even though they contain dicarboxylic acid groups. Hydrochloric acid (HCL) it acid solution, so it hydrogens would H-bond with oxygen from aspirin but not aromatic side of molecule so that why it insoluble in HCL.

Is aspirin an acid or a base?
Aspirin is a weak acid (acetylsalicylic). It's also an aromatic compound, and is slightly soluble in water.
Solution of water and aspirin an acid?
Yes it will be weakly acidic. Aspirin's scientific name is acetylsalicylic acid, with a pKa of 3.5. This would mean that for a solution of 0.1 M aspirin, the pH of the solution would be approximately 2.26.
What is sodium salicylate?
It is the sodium salt of aspirin. The carboxyl group in aspirin (COOH) is converted to COONa. This molecule is water-soluble.
How will you change the aspirin to make it water soluble?
Usually by converting it to its sodium salt, by reaction with sodium hydroxide.
What color does blue litmus paper turn when dipped in aspirin?
Aspirin is a low soluble acidic substance, so only WHEN (finally) dissolved in water, it will turn blue litmus into red. Aspirin = 2-acetoxybenzoic acid = acetylsalicylic acid = C9H8O4 = (CH3COO)-C6H4-(COOH)
Is sodium acetate soluble or insoluble in water?
Sodium acetate is soluble in water.
Why does aspirin dissolve in water?
Water is a polar molecule whereas aspirin has no overall charge so the two don't mix very well. Heating the water or adding a few drops of ethanol will make it dissolve a lot faster though. Correction: Aspirin (2-acetoxy-benzoic acid) is a moderately strong acid. It might be called a semi-polar molecule. Ethanol is similar in this respect, and is a good solvent for aspirin. As in all such cases, solubility is determined by the forces between the molecules in solid aspirin compared to the affinity between water and aspirin. The question has no trivial answer. The salts of weak organic acids are usually more soluble than the acids themselves. Adding a base such as sodium hydroxide or ammonia to the water is likely to bring more aspirin into solution - but strictly speaking, the dissolved specis is not 2-acetoxy-benzoic acid, but 2-acetoxy-benzoate.
Is sodium water soluble?
No, sodium will explode violently if touched by water. Salt, which is sodium-chloride, is soluble.
Is sodium sulphate soluble or insoluble?
Sodium Sulphate is soluble. All sodium compound is soluble in water.
Why sodium chloride is insoluble?
No that is not true. It is soluble in water.
Why sodium chloride is soluble in cold water but not in boiling water?
Sodium chloride is also soluble in boiling water.
Is sodium chloride is soluble?
Sodium chloride is very soluble in water - approx. 360 g/L at 20 0C.
