Dilution and Filtration

Dilution and Filtration Experiment

Last week in science we mixed Copper Nitrate with Sodium Hydroxide to make a bright blue precipitate. 

1. Which test tube had the most concentrated sample of Copper Nitrate?

- The first test tube 

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

- We were Diluting it.

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

                       - The first one because there were more                                        chemicals in that one than the second, third                            and fourth.

Filtering is when you can separate the solute (solid) from the solvent (liquid). 

-Separate means to spilt apart. 

Once the solvent has been filtered that is called the filtrate.
