Which of the following diggestive juices have the minimum Ph

Options

A. bile
B. gastric juice
C. saliva
D. pancreatic juice .

Explanation

To determine which of the following digestive juices has the minimum pH, we will analyze each option provided:

1. **Bile**:
- Bile is an alkaline digestive juice produced by the liver.
- Its pH ranges from 7 to 8, indicating that it is slightly alkaline.

2. **Gastric Juice**:
- Gastric juice is secreted by the stomach and contains hydrochloric acid (HCl), making it highly acidic.
- The pH of gastric juice ranges from 1.5 to 3.5, which is significantly lower than that of bile.

3. **Saliva**:
- Saliva is produced by the salivary glands in the mouth and initiates the digestion process.
- Its pH ranges from 6.2 to 7.6, which is neutral to slightly acidic.

4. **Pancreatic Juice**:
- Pancreatic juice is secreted by the pancreas and is also alkaline.
- Its pH ranges from 7.5 to 8.2, indicating that it is slightly alkaline.

Now, comparing the pH levels of all the digestive juices:
- Bile: pH 7 - 8
- Gastric Juice: pH 1.5 - 3.5
- Saliva: pH 6.2 - 7.6
- Pancreatic Juice: pH 7.5 - 8.2

From this analysis, we can conclude that **gastric juice has the minimum pH** among the options provided.

**Final Answer**: Gastric Juice (minimum pH: 1.5 - 3.5)
