a Mr Cryberg snip....
Sugar water solutions are going to have the pH of the water used to make the solution.  So, generally 7.5 more or less.

my comments...
I would guess (based more on living in a number of different locations) that the ph and quality of water from the tap will vary quite a bit.  7.5 may be an acceptable 'mean' number but certainly it has some significant variation as does the soil ph which would reasonable also effect not only water ph but also nectar/honey ph.  Quality of water is another matter but I would suspect this has more to do with the acceptability of sugar syrup as a feed for honeybees than does ph < quality of water is not necessarily inexpensive to modify but ph should be an easy and inexpensive thing to adjust.

ps.. I do highly respect any number of the 'authorities' on this board so if some of my above suspicions are incorrect do not hesitate to correct or enhance my understanding of this topic.  I do feed a good deal of sugar syrup so any adjustments to my thinking does have real world consequence.
