Why Dissolving Salt Is a Chemical Change Read More Dissolving Sugar in Water: Chemical or Physical Change? By Anne Marie Helmenstine, Ph.D. When you dissolve salt in water, thesodium chloridedissociates in Na+ions and Cl-ions, which may be written as achemical equation: NaCl(s) → Na+(...
The sugar in candy canes is soluble in water but not in oil. You would have noticed that when you place a candy cane in oil, it won’t dissolve in the same way it would in water. The solubility of a substance depends on the nature of the solvent (the substance in which the ...

The method is intended for treating waste material resulting from the manufacture of sugar-based confectionery (boiled sweets) by dissolving this in water to produce a solution for further utilisation. It comprises mixing the material with water and passing air through the mixt. for a pre-...
Hydrogen bonds are responsible for the structure of cellulose, and also for its insolubility in water and common organic solvents. The characteristic rigidity is via co-crystallization of multiple chains into parallel structures forming elementary fibrils that further organize themselves as microfibrils ...
