Sugar is a polar compound and water too a polar solvent. Polar compounds are soluble in polar solvent, and from the options sugar and common salt are polar compounds and sugar is more polar than salt hence sugar dissolves in water.

Sugar is most soluble in water because, it has six hydroxyl groups which mean it can make numerous hydrogen bonds with water, contributing to its high solubility.

NaCl: water solubility 359 g/L.
Sugar (sucrose): water solubility 2000 g/L.
However, if we look at this on a molar basis:
NaCl: water solubility 359 g/L.
(359 g/L)/(58.44 g/mol) = 6.14 moles/L.
Sugar (sucrose): water solubility 2000 g/L)/(2000 g/L)/(342.30 g/mol) = 5.84 moles/L.
So on a molar basis, the solubilities are close and one might conclude that the apparent difference lies in the difference in molar masses.
Therefore, SUGAR.

I think common salt is right.

I think salt is also very soluble.

I agree on this answer because solubility is measured by no of grams of a substance that dissolve in a certain volume of H2O.

I think we need an experiment.

I also think that answer should be NaCl.

Is the answer correct? I thought that it would have been common salt (NaCl).
