Question

1. You will be given a solution of silver nitrate from which to synthesize silver nanoprisms. The silver in the nanoprisms is Ag0. What do you need to do to the silver to get it into that form?

*Note: this question isn't asking for a specific compound; it is asking for the method needed

Answer 1

You will need to precipitate Ag from the solution.

This is known as crystallization:

There ar eplenty of processes to produce solids; the best is crystallization since you are looking for nanoprism, i.e.; a very specific shape of the crystal. This can be achieved with specific T,P and specifically batch reactor operations. If you simply saturate the mixture and cool it; plenty of solids will form. Many will be in the form of bulky solids, random crystals etc...
