you guys must be kidding. saliva is not acidic. it has the same pH as blood which is around 7.4.
amylase, the main enzyme in saliva has a pH optima of 7.4. coincidence? no. this enzyme is used to catalyse carbohydrates in the mouth since enzymes in the stomach are mostly protein-digesting enzymes.
alkalinty of saliva is a measure to somewhat neutralise the high acidity of stomach contents. you would notice if you remember the last time you vomitted. before you puke, a natural reflex to salivate occurs to protect your mouth from the stomach acids. saliva also helps to control pH on your stomach everytime you swallow.

normally slightly acidic, but it depends on what you've been eating
