Dilution and filtration

Hola! On Wednesday last week, my science class did an experiment! We used a chemical called Copper nitrate, we also used water. We diluted the solution 4 times. After that, we made a little cone out of filter paper, put it in a funnel and poured our solution in. Why did we do that? Over the next few days, crystals should've formed. 

Looking back today. there are small crystals along the side of the filter paper. I think that the experiment has worked. 


Questions - 
1. Which test tube had the most concentrated sample of Copper nitrate?

The first test-tube had the most concentrated sample of copper nitrate.

2. When we added water what were we doing to the concentration of the solution?

We were diluting the solution 

3. Which concentration of copper nitrate formed the most precipitate, why do you think this is the case?

The last one, by the 4th test tube copper nitrate, had been diluted x1000. 

Solvent: The liquid

Solute: The solid you are trying to dissolve.

Filtrate: Separating the solute (solid) from the solvent (liquid).

Precipitate: When a solid forms in a liquid.
