simple filtration using filter paper and a funnel to separate the residue from the filtrate

use of a balance, including measuring mass by difference

methods for the collection of gases including:

— collection over water (for relatively insoluble gases, or where a dry sample of gas is not required)

— collection using a gas syringe (for soluble gases or where a dry sample of gas is required)

safe methods for heating using Bunsen burners, water baths or heating mantles

determining enthalpy changes using $E_h$

volumetric analysis:

— the volume markings on beakers provide only a rough indication of volume

— measuring cylinders generally provide sufficient accuracy for preparative work, but for analytical work, burettes, pipettes and volumetric flasks are more appropriate

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

preparation of a standard solution

simple distillation using a flask, condenser and suitable heat source to separate a mixture of liquids with different boiling points

Given a description of an experimental procedure and/or experimental results, an improvement to the experimental method can be suggested and justified.
