Purpose
- Start making sample Silver film with proposed protocol
Procedure
- 3.45g of AgNO3 was weighted out and placed in a 50mL Erylenmeyer flask.
- 0.8g of Laponite clay was weighted out and placed in same Erlenmeyer flask as above.
- The 0.8g of Laponite clay was calculated in the following ways:
Cationic exchange capacity of Laponite: 0.55 milliequivilient/gram
Weight % of silver to be exchanged in Clay: 95%
Calculation is shown as follows:
___________
- 10mL of 50/50 water/ethanol solution was made by combining 5mL of water and 5mL of ethanol in a 10mL graduated cylinder.
- 10mL of water/ethanol solution was poured into Erylenmeyer flask along with a stir bar.
- The Erylenmeyer flask containing the solution is placed on stir plate for 24 hours.
