This idea of solubility can be extended to the interactions between two liquids. glucose in 95% Ethanol (slightly soluble) All other sets will follow the same pattern of answer. However, it was reported that the solubility of mannose and fructose in aqueous ethanol was higher than that of glucose at the same temperature and ethanol concentration (Hudson and Yanovsky, 1917). Glucose is a simple sugar with the molecular formula C6H12O6. This makes it somewhat polar in nature and also capable of hydrogen bonding. This is normally defined as 10 grams solute per 100 grams of solvent. Explanation for this behaviour is that all the sugars are monosaccharides or disaccharides. Solubility of sucrose in water and particularly in impure solutions are important in sugar technology. Eng.
