Question

List 4 types of equipment commonly found in the lab and identify what they each measure.

Answer 1

The four types of equipment commonly found in the lab are stir plates, graduated cylinders, pH meters, and Pasteur pipets. Stir plates are used for mixing substances, graduated cylinders for measuring liquid volume, pH meters for measuring acidity/alkalinity, and Pasteur pipets for transferring small amounts of liquids.

Step-by-step explanation:

1. Stir plates: These are used to mix substances in the lab by creating a swirling motion. They are commonly used in chemistry experiments to ensure thorough mixing of reactants.
2. Graduated cylinders: These are used to measure the volume of liquids. They have markings along the side that allow for accurate measurements of different volumes.
3. pH meters: These are used to measure the acidity or alkalinity of a solution. They provide a numerical value called pH, which indicates the concentration of hydrogen ions in a solution.
4. Pasteur pipets: These are small plastic tubes used to transfer small amounts of liquids. They are commonly used in microbiology experiments to transfer bacterial cultures or small amounts of reagents.
