The pH of saliva is almost constant but it varies depending on the measurement and various Investigators determine the pH of saliva in range of pH 5.0 to pH 8.0
This varies depending on the type of meal, if you have taken acidic meal then pH is slightly low, if you have taken alkaline meal then pH is slightly high.
Therefore, it is advisable to wash your mouth before the measurement of pH of saliva.
