1. Lab techniques

2. Measuring the volume of a liquid with a graduated cylinder:

3. What is the scale increment for the 100-mL graduated cylinder? the scale increment is 10 mL/10 graduations = 1 mL/graduation. What is the volume you should record for the solution in the image above? 53 mL

4. What is the scale increment for the 25-mL graduated cylinder? the scale increment is 5 mL/10 graduations = 0.5 mL/graduation. What is the volume you should record for the solution in the image above? 21.5 mL

5. Using a laboratory burner: Inner cone Outer cone Hose

6. Using a magnetic stirrer:
