2. Is resting saliva acidic or basic? and what is it's corresponding exact pH or if possible pH rangE?

3. Explain the whole process: what is the influence in adding acids with different concentrations(such as: 0.25%, 0.1%, 0.05%, 0.025%, and 0.0075% HCl) with Saliva and starch paste. then placing it in a water bath at 40 degree Celsius, then later testing a small portion with iodine and Benedict's test in 5 minutes intervals, until it will give a positive result for Benedict's test.

4. Explain the whole process: what is the influence in adding alkali with different concentrations(such as: 2%, 1%, 0.5%, 0.125%, and 0.065% NaOH) with Saliva and starch paste, ALSO NEUTRALIZING IT WITH HAc. then placing it in a water bath at 40 degree Celsius, then later testing a small portion with iodine and Benedict's test in 5 minutes intervals, until it will give a positive result for Benedict's test.
