Step 1
Describe the role of a chemist in an industrial setting
Answer
A chemist employed in an industrial setting, such as a pharmaceutical company, plays a vital role in the development and production of medications. Their responsibilities include conducting experiments to formulate new drugs, analyzing chemical compounds to ensure safety and efficacy, and working with a team to optimize production processes.
Chemists also play a crucial role in quality control, where they test samples of products to verify that they meet regulatory standards. They are involved in research to innovate new formulations or improve existing ones. Additionally, maintaining compliance with safety protocols and regulations is an integral part of their duty.
Step 2
A chemical principle used by the chemist
Answer
One essential chemical principle used by chemists in the pharmaceutical industry is the concept of molarity. Molarity is defined as the number of moles of solute per liter of solution, represented mathematically as:
where:
- = molarity
- = number of moles of solute
- = volume of solution in liters.
This principle is crucial for preparing solutions with precise concentrations, which are necessary for effective drug formulation and testing.
