How is mass measured using a balance?

Back

Mass is measured by difference using a balance.

Front

What are the methods for collecting gases?

Back

Gases can be collected over water for relatively insoluble gases or when a dry sample is not required, and using a gas syringe for soluble gases or when a dry sample is required.

Front

What are safe methods for heating in the lab?

Back

Safe methods for heating include using Bunsen burners, water baths, or heating mantles.

Front

How is enthalpy change determined?

Back

Enthalpy change is determined using Eh.

Front

What is volumetric analysis?

Back

Volumetric analysis involves using a solution of accurately known concentration in a quantitative reaction to determine the concentration of another substance.

Front

What is titration used for?

Back

Titration is used to accurately determine the volumes of solution required to reach the end-point of a chemical reaction.

Front

What is a standard solution?

Back

A standard solution is a solution of accurately known concentration

Front

What is simple distillation used for?

Back

Simple distillation is used to separate a mixture of liquids with different boiling points using a flask, condenser, and suitable heat source.

Front

How can experimental methods be improved?

Back

Improvements to experimental methods can be suggested and justified based on the description of an experimental procedure and/or experimental results.
