the beaker

mass of the beaker and

measure/mass between

1-2 grams of salt into the

beaker

of water for your

salt to dissolve

of salt into the flask

and pour in the 25mL

of water. Mix thoroughly

until salt completely dissolves

solution into the beaker

on the heating plate. Place

the watch glass on the beaker

as a lid. Let the water evaporate

thoroughly until beaker stops

steaming completly

evaporated the the steaming

has stopped, take the beaker

off of the heating plate with

the Rubber Tongs. Place the

hot beaker on the lab bench

for fast cooling

after the evaporation on the

electric scale. Record your

results. Then go back to the

step where you massed the

empty beaker. Subtract the

mass of the empty beaker, 

with the mass of the beaker 

with the recrystallized salt

the error% of your 

experiment. Repeat parts 

1-9 for every trial of the

recrystallization
