basically, we did a lab where we put different rocks so that they would be submerged in vinegar...to simulate acid rain...
some of the rocks made the vinegar go up...is there any way you can explain to me what happened?

In a nut shell, the rock it self contains a carbonaceous base substance like baking soda
If you add vinegar to baking soda it will made the vinegar go up the same will happen to your rock if you add vinegar to it.

The pH went up because some of the acid was consumed by dissolving the rock.

the mineral in the rock disolved into the vingar, forming another substance, making the molecules bigger. bigger molecules take up more space.
