Can be used to hold store or heat liquids?
lab equipment and usesNAMEUSEerlenmeyer flasksUsed to heat, mix, and store liquids.
The advantage to the Erlenmeyer Flask is that the bottom is wider than the top so it will heat quicker because of the greater surface area exposed to the heat.evaporating dishUsed to recover dissolved solids by evaporation.40 more rows.
What is solution measured in?
A solution forms when a solute dissolves in a solvent . The concentration of a solution is a measure of the amount of solid dissolved in 1 dm 3 of solution. When the mass of solute dissolved is measured in g, the units for concentration are g/dm 3.
What does a graduated cylinder look like?
A graduated cylinder, also known as measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured.

What lab equipment is best for transferring small quantities?
Pasteur PipettesUsing Pasteur Pipettes Pasteur pipettes (or pipets) are the most commonly used tool for transferring small volumes of liquids (< 5mL) from one container to another.
What is used to measure heat and mix large amounts of liquids?
BeakersBeakers. Beakers come in different sizes and are usually cylindrical with a spout for pouring liquids. They are specifically used to hold, mix, stir and heat liquids.
What is used to heat small amounts of liquid?
Test tube – A test tube is a glass or plastic tube used for holding, mixing, and heating small quantities of liquid chemicals.

What is used to measure chemicals?
A very powerful and sensitive instrument used to study trace amounts of chemicals in the air is a gas chromatograph (crow-MAT-oh-graf) connected to a mass spectrometer (spek-TRO-meh-ter), or GCMS. The GCMS can detect chemicals in amounts as small as a picogram. That is 0.000000000001 gram.

Which of the following is used to measure the large amounts of liquids necessary for reagents?
Volumetric BeakerWhat does a Volumetric Beaker measure? The relatively large amounts of liquids necessary for reagents.
What is used to pick up and hold apparatus?
Forceps. Used to pick up or hold small objects.
How do chemicals transfer to solids?
Many solid chemicals can be easily transferred by tipping the bottle and slowly rotating the bottle back and forth. Don’t tip the bottle up high and let the contents pour out. If a spatula is provided at the reagent bottle, you may use it. Never use your own spatula.
When mixing chemicals What should be added first?
Mixing liquids: When mixing concentrated (>10%) aqueous chemicals (such as acids, bases and oxidizers), always pour the more concentrated solution into the less concentrated one to avoid splattering. This common rule has two convenient mnemonics: 1) (AAA) Always Add Acid to water.

What is a clay triangle used for in chemistry?
A pipeclay triangle is a piece of laboratory apparatus that is used to support a crucible being heated by a Bunsen burner or other heat source. It is made of wires strung in an equilateral triangle on which are strung hollow ceramic, normally fire clay, tubes. The triangle is usually supported on a tripod or iron ring.
