General Protocol: | |||
# Pour 20mL of CuSO<sub>4</sub> stock solution(prepared on [[User:Moira_M._Esson/Notebook/CHEM-581/2012/09/21|09/21/2012]]) into a clean beaker with a magnetic stirrer. | |||
# Stir solution breifly(~1min) | |||
# Add 0.1g clay to solution while solution is stirring. '''Immediately''' start a timer. | |||
# Allow solution to stir for desired amount of time(for this experiment the time intervals 1min, 5min, and 10min will be used). | |||
# Once the time period has ended, '''immediately''' filter the solution with a '''dry''' 42 Whatman filter paper | |||
*Note: Make sure that all glassware is clean and dry. To ensure that the glassware is dry, rinse the glassware with acetone and place in an oven(~60°C) for ~5min to dry. | |||
