Find the color of the gold nanoparticles in solution.
- AYellow
- BPink
- CBlack
- Correct answerDRed
Solution
The color of a colloidal solution depends on the wavelength of light scattered by the dispersed particles, which in turn depends on the size and nature of the particles.
The finest gold sol is red in color. As the size of the particles increases, the color changes to purple, then blue, and finally golden.
Therefore, the color of gold nanoparticles in solution is red.
