The dilluting and dissolving solutions
Presented by Eva PASQUARELLI, Agathe MURARO, Paloma PATRIS y Yasmine NIDAM
START
FIRST EXPERIMENT
THE DISSOLVING SOLUTION
The material we need
- A measuring pipet
- A beaker
- A distilled water's pastic pipet
- A cup
- A 50ml's volumetric flask
- A weighting scale
STEP 1
STEP 2
Put the brown sugar in the beaker
Add water
STEP 3
STEP 4
Mix the sugar and the water with a spatulate
Put it in a volumetric flask of 50ml and add water next to the line
FINAL STEP
RESULTS
Mix the volumetric flask
The solution became homogeneous
SECOND EXPERIMENT
THE DILLUTING SOLUTION
The material we need
- A 100ml's volumetric flask
- A beaker
- A ink cartdridge
- A plastic pipet of distilling water
STEP 1
STEP 2
Put the ink in the volumetric flask
Add water
STEP 3
STEP 4
Add more water
Add water next to the line
FINAL STEP
RESULTS
Mix the volumetric flask
the solution became less concentrated
To conclude
Both experiments were interesting to make. Also, our hypothesis were good. indeed the dissolving solution became homogeneous because the brown sugar and the water mixed all together and the diluting solution became less concentrated thanks to the water.
