Dissolving of solids

Question

![Sucrose|525x359](upload://mh0tZZ8EzHAcMFF6zTCJ6PW6fhN.gif)

Hi all,

In fact this is general chemistry question. But i think answers also can help food professionals.

Question is that;

When a solid is dissolved in a liquid, **which size are the dissolved solids in solution**? Nanometer, some of micrometer or both?

Sucrose molecule size is *a* = 1.08631 nm, *b* = 0.87044 nm, *c* = 0.77624 nm

so when sucrose is dissolved in water all molecules are alone or some of them can be together?
*I think all molecules are not alone.*

Answer 1

Hi,
As a general rule, smaller ones should dissolve easily followed by next sizes and so on.
However in this example all of them are in nm and the sizes are very close to one another. In fact we could call those as just nanosized particles. Hence the question may not be relevant in this case.
Also to note that when we talk about nano and micro particles in actual preparations, and considering its differences in the surface area they might work differently. Hence such approaches are used in emulsion preparations for comparatives nano and micro versions.
Hope it helps in some or the other way.
