DNL PRESENTATION

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.
