PERFORMANCE
ASSIGNMENT Lab Two |
In this reaction, the interaction between aluminum and copper chloride will be observed.
Carefully study the characteristics that indicate a change is taking place. Make your observations complete and be sure to use both qualitative and quantitative indicators.
Objectives:
1.
Learn to follow laboratory
instructions.
2. Learn to make note of, and
describe chemical change.
3. Identify and use appropriate
pieces of equipment to make observations.
Procedure:
1.
Obtain a beaker, copper chloride and a sheet of aluminum foil.
2.
In an observation table, describe the physical characteristics of copper
chloride and aluminum.
3.
Add 25 ml of distilled water to the beaker and mix in one level scoop of
copper chloride. Stir the crystals
until they dissolve. Observe and record the physical characteristics of the
solution.
4.
Place a piece of loosely wadded aluminum foil into the solution. Let the aluminum foil set in the solution
for about five minutes. Observe and
record any changes that take place.
5.
Use the thermometer to record any temperature changes from start to
finish.
