8. What are some common tools used by chemists in their work?

This question can help the interviewer get a better idea of your chemistry lab skills by seeing how familiar you are with common tools. You can answer this question by naming several tools and briefly describing what they’re used for.

Example: “Some common tools chemists use include beakers, flasks, test tubes, pipettes, burettes, burners, balances, scales, thermometers, crucibles, distillation equipment, gas masks, safety goggles and fume hoods. Beakers, flasks and test tubes are all glass containers that are often used to hold liquids or solids. Chemists use these vessels to measure substances, mix solutions and heat chemicals. Pipettes are also made of glass and are used to transfer small amounts of liquid from one container to another. Burners are used to heat up substances in order to change their state. Balances are used to weigh substances accurately. Scales are similar to balances but have digital displays instead of weights.”

9. What education is required to become a chemist?

Employers may ask this question to learn about your educational background and determine if you have the necessary qualifications for the job. If you don’t have a degree in chemistry, explain what other education or experience you have that makes you qualified for the position.
