Mixing and Separating

For today's 2 hours of science, we are doing two in one experiment! We are going to make our own mixture then we are going to create a filter to filter the mixture we are creating.

KEYWORDS -  

solvent - The thing doing the dissolving (Liquid)
solute -  The thing being dissolved (Solid)
Solution - The mixture that has formed
filtration - Separates particles based on size
filtrate - liquid after it has been filtered
mixture - 2 or more substances together
solubility - ability to dissolve

AIM - 
To separate a solution from a precipitate (Precipitate is the name for a solid that forms in a liquid during a chemical reaction.)

MATERIALS - 

Copper sulfate
Sodium carbonate
Beaker
Funnel
Filter paper
Conical flask
Stirring Rod 

METHOD - 

1 - Add 50ml of sodium carbonate + copper sulfate into your beaker.

2- Mix the two liquids together with your stirring rod.

3- fold your filter paper into quarters and fold it out so it is in a funnel shape and slip it into the funnel. 

4 - Place your funnel and filter paper into the conical flask 

5- Pour in your mixture from the beaker and watch the magic happen! 

RESULTS - 

We added 50ml of each (Sodium Carbonate which was clear and colorless + copper sulfate still clear but had a twinge of light blue) They are both clear but when mixed together become an opaque blue. When the mixture was filtered the filtrate came out clear and colorless just like how the sodium carbonate had started off. What was left were the bigger particles that couldn't get through the filter paper and had become solid. The particles that remained on the top became a very gluggy texture that reminded me of glue, which was unlike the liquid filtrate. Though the remains on the top were really chunky, almost a slimy texture the filtrated mixture came out in a steady flow of drips that joined the transparent liquid down the bottom. The filtrate was the sodium carbonate and the blue solid was the copper sulfate.

Expansion and contraction

Today in chemistry class we were looking at four different actions to do with matter, Expansion, contraction, Convection, and conduction, We then had to choose one of them and create an animation explaining what the action is. I partnered up with my mate and we did animation on expansion and contraction. 

Particle Theory

During today's lessons in chemistry, we were learning about the matter! Under the topic of matter, we are casting an experiment on Particle Theory and diffusion. Particle theory is the theory that all matter is made up of heaps of very small particles,  All particles in a pure substance are the same, there is a space between all particles, particles are always moving, There are attractive forces between particles and Temeprature affects the speed at which particles move. Diffusion is where you are mixing different matter particles so it moves from a high concentration to a low concentration.

AIM - To investigate the effect of temperature on the rate of defusion.

HYPOTHESIS - I think that it will defuse faster in hot water rather than cold water, as hot water moves faster compared to cold water

METHOD - We filled the 2 Petri dishes with water, one with hot water, one with cold water. we then got two pinches of potassium permanganate and tipped them into the two dishes at the same time with the same amount of the potassium permanganate to see clear results.

CONCLUSION - The potassium permanganate spread faster in the warm water compared to the cold water telling us that the potassium permanganate diffused faster in hot water. 

DISCUSSION -
This was because the warm water particles were already moving fast due to the kinetic energy, and the potassium permanganate was already moving so when they met they were moving faster than the cold water, causing them to bump into each other quicker and making the potassium permanganate spread faster.
