"How does sugar affect the surface tension of water?

 

Answer:

Sugar affects the surface tension of water because when the dissolution process takes place, causing the breaking of the hydrogen bonds in water due to the hydration energy that is generated by the interaction of sugar with the molecules of water it leads to a reduction of the surface tension. Further based on the results of the axisymmetric drop shape analysis (ADSA) used for the surface tension determination, it has been found that sugars such as dextrose and dextran decrease the surface tension of water, (Hoorfar, 2006)
