e. blood, pH 7.45

Step-by-Step Solution

Answer

(Part a). acidic

(Part b). acidic

(Part c). basic

(Part d). basic

(Part e). basic

Step 1: Given Information (Part a)

An acid is any hydrogen-containing substance that is fit for donating a proton (hydrogen ion) to another substance. A base is a particle or ion ready to acknowledge a hydrogen ion from an acid. Acidic substances are normally identified by their acrid taste.

Step 2: Explanation Part (a)

Saliva is acidic in nature as its pH is less than 7.

Step 3: Explanation Part (b)

Urine is acidic in nature as its pH is less than 7.

Step 4: Explanation Part (c)

pancreatic juice is basic in nature as its pH is greater than 7.

Step 5: Explanation Part (d)

Bile is basic in nature its pH is greater than 7.

Step 6: Explanation Part (e)

Blood is basic in nature as its pH is greater than 7.
