Question	Answer
It is a laboratory equipment used in analytical chemistry for the dispensing of variable amount of a chemical solution and measuring that amount at the same time. An acid burette is a glass vial with graduation marks. It is used in the laboratory for accurately measuring and dispensing liquids.	Acid Burette
It is a laboratory equipment used to connect pieces of ground glass joint glassware to each other, to a vacuum source, or to a water aspirator. It is also used to lead liquids from a condenser to a receiving flask during distillation.	Adapter
It is piece of laboratory equipment used to produce an open flame. It is usually made of glass but can also be made of brass, aluminum or stainless steel. It is otherwise called as alcohol burner or spirit lamp.	Alcohol Lamp

is a separation technique based on how the different components in a mixture have different affinity for the stationary and mobile phase	chromatography
is a separation technique used to separate components of a liquid mixture by a process of heating and cooling	distillation
is a separation method used to separate of a mixture of a liquid with a dissolved solid, involving removal of a liquid by evaporating it and leaving behind a solid	evaporation
is a separation technique used to separate the components of a mixture containing an undissolved solid in a liquid by using a funnel lined with filter paper to retain the solids while letting the liquid through?	filtration
is the process of separation of insoluble materials from a liquid where normal filtration does not work well. The principle is that the denser particles are forced to the bottom and the lighter particles stay at the top when spun rapidly.	centrifugation
