SCIENCE INVESTEGATORY

PROJECT(S.I.P.)

Does the size of the solute affects on how fast it dissolve in the

solvent?

I. PROBLE

M

Yes, the size of the solute affects on how fast it dissolve in the

solvent.

II. HYPOTHESIS

III. MATERIALS

1. 2 Beakers

2. 4 tsp. of salt

3. 2 Stirring

Rods

4. Graduated Cylinder

5. 200 mL of Water

IV. VARIABLES

IV: size of the salt DV: how fast it dissolve in waterCV: amount of salt Amount of water Temperature of water Time or minutes of stirring

V. TABLE OR DATA

MATERIAL WHICH DISSOLVE FASTER IN 100mL

OF WATER

OBSERVATION

It dissolve on the water but it is slower than the crushed saltIt also dissolve in the water and its faster than the uncrushed salt

2 tsp. of uncrushed salt

2 tsp. of crushed salt

VI. CONCLUSION

Therefore, we conclude that the crushed salt is faster to dissolve than the granules of salt. Thus, the size of the solute affects how fast it dissolve on water with the same amount of water and temperature
