Chemistry Lab Exam Equipment

What is this?

Volumetric Flask ( used for measuring accurate volumes of liquid materials for laboratory experiments)

What is This

Erlenmeyer Flask ( used for mixing, swirling, and storing liquids in laboratory settings, not as accurate for measurements compared to volumetric flasks. )

What is this?

Beaker (used in laboratories for holding, mixing, and heating liquids during experiments or chemical reactions)

What is this?

volumetric pipette (used for the accurate transfer of a specific, fixed volume of liquid)

What is this? and how do you use it?

volumetric pipette bulb (used to draw liquid into a pipette and to dispense it accurately)

What is this? Which Lab would you use it in?

burette - Used in titration lab (used to accurately dispense and measure precise volumes of liquids, particularly in titrations. Measured in mL)

What is this?

Bunsen Burner (used to heat substances, to combust substances, and to sterilize objects on high heat). To ensure proper usage, ensure a blue double ring flame is seen

What is this?

Phenolphthalein Indicator (primarily used as a pH indicator in acid-base titrations, turning colorless in acidic solutions and pink to red in alkaline solutions)

What is this? What lab is this used in?

Qualitative folded paper - sequential chemical analysis (used in labs to filter mixtures, usually separating solids from liquids.)

What is this? What lab is it used in?

calorimeter - Specific Heat Capacity (used to measure heat changes during chemical or physical processes)

What is this?

(Also could look like the image on the left) temperature probe (Temperature probes connected to a computer allow for real-time temperature monitoring and data logging.)

What is this?

scoopula (spatula-like tool used in chemistry labs primarily for transferring solid chemicals.)

What is this?

stirring rod (used for mixing liquids, or solids and liquids) Also used in sequential chemical analysis to ensure not to much liquid goes in at once and it’s a more precise flow.

What is this? Which Lab was this used?

Crucible tongs -Percentage Composition (used to lift a hot crucible from an item which cannot be handled with bare hands)

What is this?

porcelain crucible and lid- preferably slightly cracked (used to heat metals, salts, and other solid substances, especially when high-temperature melting is required)

What is this?

clay triangle ring (supports a crucible and allows the flame to heat the crucible directly.)

What is this?

colorimeter (used to measure the concentration of colored compounds in a solution by determining how much light of a specific wavelength is absorbed by the solution)

What is this?

mass balance (used to track the movement and transformation of matter within a system, ensure to 0 it when neccessary)
