Following are pH ranges for several human biological
materials. From the pH at the midpoint of each range, calculate the
corresponding 3H3O1 4. Which materials are acidic, which are basic, and which
are neutral?

 (a) Milk, pH 6.6–7.6

 (b) Gastric contents, pH 1.0–3.0

 (c) Spinal fluid, pH 7.3–7.5

 (d) Saliva, pH 6.5–7.5

(e) Urine, pH 4.8–8.4

 (f) Blood plasma, pH 7.35–7.45

 (g) Feces, pH 4.6–8.4

 (h) Bile, pH 6.8–7.0
