Really depends on what the sugar is dissolved in. You can't really take the pH of a solid, therefore if you are talking about table sugar in its normal form then you cannot determine the value.
However, if the sugar is in solution then you can test the pH. The pH will vary however depending on how dilute the solution is. The more water you add and the more dilute the solution becomes, the greater the pH change.
You can either determine the pH by a pH meter, electronically. Or you can solve for it mathematically if you know the Ka value of the particular sugar in solution.
Ka = [H3O+][A-] / [HA]
Then, you can plug in values for [A-] and [HA] by using charge balance and mass balance equations and you can solve for [H3O+]. Once you have [H3O+] you can solve for pH using the equation:
pH = -log([H3O+])
Hope this helps.

Sugar is non-ionic and in solution in pure water should have a pH of 7

sugar is not a liquid, or gas..
this might help out
