Sodium Silicate Polymer Lab

Q1: What characteristics are similar between your two types of polymers you have made?
A1: Poly 1 is the polymer from glue and Poly 2 (Put Picture Here)


Q2: Most Commercial polymers are carbon based. What similar properties do carbon and silicon share that may contribute to their abilities to polymerize?
A2: Silicon and carbon both can give up or obtain four electrons. This is why they bond to so many other elements.  They also are both in group 14 in the periodic table.


Q3: Plastics are made of organic (carbon based) polymers. What similar properties does silicone share with plastics?
A3: They both are cloudy and white tinted.  It also bends fairly easily but holds its shape.


Q4: How did you know that a chemical reaction had taken place when the alcohol contacted the solution?
A4: Because the matter changed from a liquid to a solid.  That can only happen when there is a chemical change.


Q5: How could you find out what liquid was forced out of the ball as it was formed?
A5: By examining the contents of the ball, finding them, and comparing them to the contents of the solution before mixing.


Q6: How does your ball compare to other groups?
A6: Ours is bigger and has less veins than other groups.  Ours also retained a dome shape while others stayed spherical.
