There are two separate methods as there are two separate hypotheses.
Method 1
11. Using
a pipette measure 1/3 of
100ml methanol and pipette into a 100ml graduated cylinder.
22. Using
a pipette measure 2/3 of 100
ml distilled water and pipette into the same 100ml graduated cylinder.
33. Stir
using a stirring rod and wait for all air bubbles to settle.
44. Record
the volume displayed on the 100ml graduated cylinder.
55. Repeat
steps 1 to 4 another two times.
66. Repeat
steps 1 to 5 using ethanol.
77. Repeat
steps 1 to 5 using butanol.
88. Using
a pipette measure 1/4 of 100ml ethanol and pipette into a 100ml
graduated cylinder.
99. Using
a pipette measure 3/4 of 100 ml distilled water and pipette into
the same 100ml graduated cylinder.
110. Stir
using a stirring rod and wait for all air bubbles to settle.
111. Record
the volume displayed on the 100ml graduated cylinder.
112. Repeat
steps 8 to 11 another two times.
113. Repeat
steps 8 to 12 using ethanol.
114. Repeat
steps 8 to 12 using butanol.
115. Using
a pipette measure 1/5 of 100ml methanol and pipette into a 100ml
graduated cylinder.
116. Using
a pipette measure 4/5 of 100 ml distilled water and pipette into
the same 100ml graduated cylinder.
117. Stir
using a stirring rod and wait for all air bubbles to settle.
118. Record
the volume displayed on the 100ml graduated cylinder.
119. Repeat
steps 15 to 18 another two times
220. Repeat
steps 15 to 19 using ethanol.
221. Repeat
steps 15 to 19 using butanol.
Method 2
11. Mix
up the optimum ratio of methanol, ethanol and butanol.
22. Record
the contraction of each alkanol and water mixture.
33. Place
each mixture in water bath set to 40°C and leave for 24 hours.
44. Record
results.
55. Repeat
steps 1 to 4 two more times.
66. Repeat
steps 1 to 2.
77. Place
each mixture in a fridge set to 2°C and leave for 24 hours
88. Record
results.
99. Repeat
steps 6 to 9 two more times.
