Experiment 1: Common Laboratory Operations Flashcards
where the fuel and air mixes
barrel
entrance of the air
air hole
regulates/controls the amount of fuel has to be combusted
gas spud
regulates/controls the amount of air coming in and to close and open the air holes
collar
entrance of the fuel gas
gas inlet
supports the bunsen burner
base
valves the controls the fuel gas coming in to the gas spud
gas regulator
place of ignition
mouth
- blue color
- open air holes
- maximum air needed
- complete combustion
nonluminous flame
- yellow color
- close air holes
- less amount of air needed
- incomplete combustion
luminous flame
curve line present in a liquid inside the container
meniscus
used in transparent liquid
lower meniscus
used in colored and opaque liquid
upper meniscus
guide the flow of the fluid, prevent the spillage of water at the side of the wall of the container
glass rod
it is the separation of each components/substances in a given mixture
process of separation
process in which solid converts into gas directly without converting into liquid
sublimation
process of separating suspended solid matter from a liquid or gaseous fluid
filtration
process for the separation of mixtures of immiscible liquids or of a liquid and a solid mixture such as a suspension
decantation
collecting of molecules by the external surface or internal surface
adsorption
liquid becomes gas
evaporation
substance clinging at the bottom of the watch glass, white crystals
naphthalene
substance left in the beaker
salt, coloring and sand
clear liquid left at the container
supernatant liquid
solid left at the container
residue
used to absorb the coloring and odor
activated carbon
clear liquid that pass through the filter paper is called
filtrate
