Tools and Methods in The Chemical/Chemistry Laboratory
Hi
guys, stay with me yaaaa J
Here,
I want to share about the function of some tools in the chemistry laboratory…
Let me do it J
“Beaker
glass”
Beakers hold and heat solution that
will not release gases when reacted.
“Beaker
tongue”
Used to hold and move beaker
containing hot liquids.
“Erlenmeyer
flask”
Same like a “beaker glass” , but for
may release gases during a reaction.
“Florence
flask”
Used for the mixing of chemicals or
solution.
“Graduated
cylinder”
Used to measure volumes of liquids.
“Watch
glass”
As a place of solids to be weight.
“Litmus
paper”
Used to identify acids or bases.
“Dropper
pipet”
Use to transfer a small volume
liquid.
“Graduated
pipet”
Same like “Dropper pipet” , but has exact volumes.
“Funnel”
Used to aid in the transfer of
liquids from one vessel to another.
“Electronic
Balance”
Used to weight the solids.
“Scoopula”
Used to dispense solid from ther
containers.
“Burner”
Used for heating liquids and solids.
“Fume
hood”
Is an exhaust fan for smelly or
dangerous fumes.
“Crucible
and cover”
Are used for heating certain solids,
particularly metals to very high temperatures.
“Wash
bottle”
As a place of distilled water
(aquadest).
For
the next, there are some methods and process in the chemical laboratory.
“Distillation”
Is a widely used method for
separating mixtures based on differences in the conditions required to change
the phase of components of the mixture.
“Decanting”
Decanting is a chemical laboratory process
used to separate mixtures.
“Fermentation”
Is a metabolic process in which an
organism corverts a carbohydrate, such as starch or a sugar into an alcohol or
an acid.
“Titration”
Is a technique used in analytical
chemistry to determine the concentration of an unknown acid or base.
