Answer 13

Uses flames and should not be used for flammable liquids

Question 14

Electronic balances

Answer 14

Used to weigh the mass of solids either tear the balance or weigh by difference

Question 15

When is a desiccator used

Answer 15

During gravimetric analysis

Question 16

Function of desiccator

Answer 16

Allows the hot crucible to cool without absorbing water it does not dry the crystal. Desiccator is a dry environment due to being sealed and having a chemical in the base which maintains a dry environment.

Question 17

Separating funnel

Answer 17

Used during solvent extraction a substance is dissolved in one solvent and added to the funnel the second Immiscible solvent is added to the funnel it is then shaken ti mix the solvents and partition the solute between the two cap opened to drain bottom layer

Question 18

Büchner funnel

Answer 18

The funnel is placed on top of a flask which is attached to a water or vacuum pump this allows for quick separation of solids from solvents. Solid left in funnel and dried and collected easily

Question 19

Distillation (round bottomed) flask

Answer 19

used for distillation, the process of separating a mixture of liquids with different boiling points through evaporation and condensation

Question 20

Condenser

Answer 20

Condensers are used in distillation to cool the hot vapors, condensing them into liquid for separate collection

Question 21

Glassware with round glass joints (quick fit or similar)

Answer 21

The use of jointed glassware helps to avoid spills and leaks of potentially harmful and often valuable substances during experiments.

Question 22

Thin layer chromatography apparatus

Answer 22

Used to separate mixtures of compounds based on differences in polarity and size
