Copper Chloride Lab

Today in class we had a lab where we had to create a solution of Copper Chloride with a concentration of O.1 M and then compare to samples Mr.Doktor set up. The solution that matched the solution you create (in terms of colour/shade) is the winner.

Materials:
Beaker
Graduated Cylinders
Stir Rod
Test Tube Stand
Water
Copper Chloride

Procedure:

Take about 5g of Copper Chloride and place it into a plastic dish
Take your plastic dish and pour the copper chloride onto a piece of wax paper
Take the wax paper and place it on your weighing scale
Weigh and record the total mass of the copper chloride
Put at least 25-50 mL of water in a graduated cylinder
Take an amount from the recorded amount of copper chloride with your scoopula
Put the same amount of copper chloride into the 25-50mL of water
Slowly stir the solution with a stir rod
Compare with Mr.Doktors solution and choose the closest shade of blue that matches yours
Repeat the procedure a few more times for consistent results

NECESSARY MATH:

0.050L/0.025L x (.1mol/L\) x (134.5g/mol) = ? g
