Q & A

What is the primary purpose of wearing safety gear in a chemistry lab?

The primary purpose of wearing safety gear, such as goggles, latex gloves, and a lab coat, is to protect the user from coming into contact with chemicals, both knowingly and unknowingly.

What is an electronic balance used for in a chemistry lab?

An electronic balance is used for measuring the mass of a substance or chemical, providing a precise reading based on the displacement of a pan due to gravity.

What is the function of a ring stand in a laboratory setting?

A ring stand is used as support to clamp laboratory glassware and other equipment in place to prevent them from falling down or coming apart.

How is a wire gauze used in conjunction with a ring stand?

A wire gauze is used to support a container, such as a beaker, on a ring stand while it is being heated, often with a fiberglass or ceramic center for stability.

What precautions should be taken when using a Bunsen burner?

When using a Bunsen burner, one should be careful not to place flammable materials like cloth or certain chemicals, such as petrol, near it to prevent a fire hazard.

What is the purpose of a beaker in a chemistry lab?

A beaker is a glass apparatus used to hold, mix, and heat liquids, making it versatile for various laboratory procedures.

What is the role of beaker tongs in a laboratory?

Beaker tongs, which resemble a larger version of scissors, are used to handle beakers, especially when they are hot or need to be moved safely.

What is a crucible and how is it used in a chemistry lab?

A crucible is a ceramic pot used for holding chemicals during heating at very high temperatures, allowing for reactions that require intense heat.

What is the purpose of a clay triangle and how is it used?

A clay triangle is a metallic triangle used to support a crucible during heating, ensuring stability and preventing the crucible from direct contact with the heat source.

What is the function of an evaporating dish in a chemistry lab?

An evaporating dish is a wide, ceramic dish used to heat liquids for evaporation, allowing for the concentration of solutions or the separation of components.

What is the purpose of a volumetric flask and how is it used?

A volumetric flask is a round flask with a long neck and flat bottom, used to prepare solutions to an accurate volume. It has a calibration mark to indicate the fill line and comes with a special cap to prevent contamination and leaks.
