Dilution and Filtration Blog

 Intro: 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 we doing to the concentration of the solution?

     - You are diluting it 

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

     - The first test tube because there was more chemicals in that test tube rather than the other 3. 

Key terms: 

 

Filtering Is when you can separate the solute (solid) from the solvent (Liquid).

Separate means to split apart.

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

Aim: Build a pasta rover that can travel 1m down a ramp then 1m across the floor.

Equipment:

• Lasagne Sheet

• Fettuccine
