Question

Procedure: Solution A: Take 0.015g of NaAuCl4 and add 1.5 ml of dI water in a vial Stepl: Take 0.012g of Phosphorus reducing agent and add 35 ml of dI water in a 50 ml beaker. Stir this solution with a magnetic stirrer Step 2: After complete dissolution of Phosphorus reducing agent, add0.025gm of Gum arabie powder with continued stiring. Step 3: After complete dissolution, add solution A drop by drop with continued stirring. Record the color of the solution changing from light yellow to dark violet. Step 4: Continue stirring for 10 minutes. Preparation of nanochains: Leave the gum arabie stabilized gold nanoparticles in a sample vial for 30 days Observations: Observe the color change and record. Record UV-Vis spectrum for the solution and append with your laboratory report. Take Transmission Electron Microscopy (TEM) image of gold nanoparticles on first and 30th day of their synthesis.

Explanation / Answer

The current problem analyzes gold nanoparticles with various stabilizing agents.
