Answer :
Final answer:
Pancreatic juice has a pH of 7.9, indicating it is alkaline. Soil acidity or basicity can be detected by measuring its pH, with values below 7 being acidic, neutral at 7, and above 7 being alkaline. Methods like litmus paper and universal indicators are commonly used for this purpose.
Explanation:
Is Pancreatic Juice Acidic or Alkaline?
The pH of pancreatic juice is 7.9, which is greater than the neutral pH level of 7.0. This indicates that pancreatic juice is alkaline. In the context of body fluids, the alkaline nature helps to neutralize the highly acidic environment of the stomach as food enters the small intestine, aiding in digestion.
How to Detect Soil Acidity or Basicity
To determine whether soil is acidic or basic, one can measure the pH. Soil pH is gauged using the same scale that applies to liquids, where:
- A pH below 7 indicates acidic soil.
- A pH of exactly 7 indicates neutral soil.
- A pH above 7 indicates alkaline soil.
Common methods for measuring soil pH include:
- Litmus paper: This indicates whether the soil solution is more acidic or basic by changing colors.
- Universal indicator: A more comprehensive test that shows a range of pH values.
Soils typically have a pH range from 3 to 10. Most agricultural soils are optimal around a pH of 6 to 7.
