Dilution and filtration

Last week in science we mixed copper nitrate with sodium hydroxide to make a bright blue precipitate.
 
Which test tube had the most concentrated sample of copper nitrate? The first one was the most concentrated because it was all chemicals and had no water to water it down.

When we added the water what were we doing to the concentration of the solution? It caused the chemicals to be less concentrated
