Jams and jellies have a ph in the lower part of the 3s, and not generally up near 4.  According to the site I am linking to, the ph of jam and jelly is around 3.1 to 3.5.

Interestingly, this overlaps with things that you would really thing of as acidic - things like vinegar.   Vinegar has a ph from 2.0 to 3.4.

The ph of jams and jellies comes largely from the fruits the jams and jellies are made from.  Sugar has a ph around 5 to 6, but fruits like strawberries have phs around 2.3 to 3.
