Hypothesis: The polymer will be stronger or weaker because of the amount of sodium silicate and ethyl alcohol.
Materials:
Sodium silicate (water glass) solution, 12 mL
Ethyl Alcohol 3 mL
2 small beakers
Stirring rod
Paper towels
Procedure: Measure out 12 mL of sodium silicate then pour it into one of your small beakers. Now place 3 mL of ethyl alcohol in another small beaker. Then slowly add the alcohol to the sodium silicate. Get your stirring rod and use a slow circular motion until the substance is solid. Now place the polymer into your plam and roll it around until it becomes a ball almost it can still have some bumps. Dispose of as instructed.
Results:
The 1st picture illustrates how the Sodium Silicate and Ethyl Alcohol should look before mixing. The 2nd is how they look when they have been stirred a little bit. The 3rd is the final product of the two
Conclusion:
Well we made a polymer our of our monomers! My hypothesis wasn’t exactly directed to the question thus proved wrong ultimately. This could help because it gives us experience in how to make polymers. When there is at least two monomers and a cross-linking agent you can make a polymer. We had no problem with this lab at all. We could perhaps use this experiment to re-create it with either more or less sodium silicate and/or ethyl alcohol! I would change the amounts of the monomers so we could maybe have a larger polymer when made.
