What causes my saliva to be foamy in my mouth? Does that mean it is acidic?

In brief: No

Saliva is always foamy because it contains some mucus to make it slippery.
Generally, ignore stuff about "acid" and "alkaline" at pop websites; it's often totally made up. The foam produces bubbles which get swallowed, and this accounts for much of ordinary intestinal gas, and why talking a lot and chewing gum makes people pass more of it.
