Ionic Equilibrium

Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.

Arrhenius Acid

Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.

Bronsted Lowry Base In Inorganic Chemistry

Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.

Question

### Analysis of Biological Fluids Based on pH Levels

#### (c) Urine
- **pH = 7.60**
- Determine the nature of urine by selecting one of the options:
- ⚪ acidic
- ⚪ basic
- ⚪ neutral

#### (d) Saliva
- **pH = 7.00**
- Determine the nature of saliva by selecting one of the options:
- ⚪ acidic
- ⚪ basic
- ⚪ neutral

#### (e) Pancreatic Juice
- **pH = 7.90**
- Determine the nature of pancreatic juice by selecting one of the options:
- ⚪ acidic
- ⚪ basic
- ⚪ neutral

### Explanation:

Biological fluids have different pH levels based on their function and environment in the body:

- **Urine**: Typically slightly acidic but can range from acidic to basic depending on diet and health.
- **Saliva**: Generally around neutral (pH 7) as it helps to neutralize acids in the mouth.
- **Pancreatic Juice**: Slightly basic, which aids in the digestion of food as it enters the small intestine.

#### Instructions:
For each fluid, analyze the pH value given and select whether the fluid is acidic, basic, or neutral based on the pH scale:
- **Acidic**: pH less than 7
- **Neutral**: pH equal to 7
- **Basic**: pH greater than 7

The pH values listed in Table 9.1 are generally the average values for the listed materials. Most natural materials, such as body fluids and fruit juices, have pH values that cover a range for different samples. Some measured pH values for specific body fluid samples are given below. Convert each one to \([H_3O^+]\), and classify the fluid as acidic, basic, or neutral.

(a) blood, pH = 7.50

- [Text Box] M

- Options:
- acidic
- basic
- neutral
