QuestionAnswer
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
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. Base burets are used for base titrants. Basically, this is used in titrations where the analyte is an acid.Alkali/Base Burette

is a separation technique based on how the different components in a mixture have different affinity for the stationary and mobile phasechromatography
is a separation technique used to separate components of a liquid mixture by a process of heating and coolingdistillation
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 solidevaporation
