Chapter 2: Q9P (page 54)

Are the following body fluids acidic or basic?

  1. Bile (pH=8.4)
  2. Urine (pH=5.9)
  3. Spinal fluid (pH=7.4)

Short Answer

Expert verified
  1. Basic
  2. Acidic
  3. Basic

Step by step solution

01

Understanding the pH scale.

The PH stands for potential of hydrogen which is used to denote whether a compound is acidic or basic.

It is denoted on a scale of 1 to 14. A pH of 7 is considered to be neutral, a pH less than 7 is considered to be acidic and a pH greater than 7 is basic in nature.

02

a. Determining whether the body fluids are acidic or basic.

Bile, pH given is 8.4. As it is more than 7, bile is considered to be basic in nature.

03

b. Determining whether the body fluids are acidic or basic.

Urine, pH given is 5.9 which is less than 7, thus urine is acidic in nature.

04

c. Determining whether the body fluids are acidic or basic.

Spinal fluid, pH given is 7.4 and is more than 7, thus spinal fluid is basic.
