Q & A

What is the function of an Erlenmeyer flask in a chemistry experiment?

The Erlenmeyer flask is used as a container to mix solutions or as a vessel for a solution during titration.

How does a volumetric flask help in preparing solutions?

A volumetric flask is used to dilute a solution to a specific volume, with a marked line indicating the exact volume needed.

What is the purpose of a glass funnel in a laboratory setting?

A glass funnel assists in pouring liquids into containers, especially when the container's opening is narrow.

How is a measuring cylinder different from a beaker?

A measuring cylinder is designed for accurately measuring the volume of liquids, while a beaker is used for stirring, mixing, or heating substances without precise volume measurements.

What does a mortar and pestle do in a chemical experiment?

A mortar and pestle are used to grind substances into a fine powder for easier mixing or reaction in experiments.

Why is a pH meter considered more precise than pH paper?

A pH meter provides a digital reading of a liquid's pH level, offering a more accurate and precise measurement compared to the color-based pH paper.

What is the purpose of a Bunsen burner in laboratory experiments?

A Bunsen burner is used for heating substances in the lab, often for processes requiring a flame, such as sterilization or heating solutions.

How does a buret help during titration?

A buret is used to precisely measure and dispense liquid reagents during a titration, with a valve to control the flow of liquid.

What is the role of a centrifuge in a laboratory?

A centrifuge spins samples at high speeds to separate substances based on their density, typically used in separating solid and liquid components.

Why is a fume hood necessary in a laboratory?

A fume hood is essential for ventilating harmful gases and fumes, ensuring the safety of individuals working with volatile chemicals.
