Initial buret reading (A) =

Final Buret reading (B) =

Total volume used = 

The image shows two close-ups of graduated cylinders, demonstrating how to accurately read liquid volumes: 

1. **Left Graduated Cylinder**:
   - The liquid level is at the 10 ml mark.
   - The meniscus, or the curve of the liquid surface, slightly dips below the 10 ml line.
   - The correct reading is taken at the bottom of the meniscus, which aligns with the 10 ml mark.

2. **Right Graduated Cylinder**:
   - The liquid level is at the 24 ml mark.
   - Similarly, the meniscus dips slightly below the 24 ml line.
   - The correct reading is at the bottom of the meniscus, aligning with the 24 ml mark.

**Explanation**:
When measuring liquids in a graduated cylinder, it's important to view the cylinder at eye level and read the measurement at the bottom of the meniscus to ensure an accurate reading. The meniscus forms due to the liquid's surface tension and the adhesion between the liquid and the cylinder walls.
