What happens when you mix PVA and borax?
In this experiment, a polymer (polyvinyl alcohol) chemically reacts with borax to form a crosslinked polymer network. Individual polymer chains are formed by covalent bonds, which are strong bonds. In making slime, the individual polymer chains are bound together by weak hydrogen bonds.
What is the chemical reaction between glue and borax?
Borax dissolves in water into sodium ions, Na+, and tetraborate ions. Hydrogen bonds form between the borate ion and the OH groups of the polyvinyl alcohol molecules from the glue, linking them together to form a new polymer: slime.
What is the chemical formula for polyvinyl alcohol?
(C2H4O)x
Polyvinyl alcohol/Formula
What is the chemical equation for slime?
Its chemical formula is often written as Na2B4O7 ⋅ 10 H2O, though more recent work has characterized the molecule as Na2[B4O5(OH) 4] ⋅ 8 H2O. (Borate structure can be somewhat complicated.) Glue- the stereotypical white school glue- contains polyvinyl alcohol, a synthetic polymer.
What is the chemical formula for borax?
Na₂[B₄O₅(OH)₄]·8H₂O
Borax/Formula
Is Borax a monomer?
It is definitely a monomer. The chemical formula for borax is easily found with a simple search http://en.wikipedia.org/wiki/Borax.
Is borax a polymer?
You can make a polymer-based material similar to Silly Putty at home by mixing together water, borax and Elmer’s Glue. Elmer’s is made up of polyvinyl acetate, which is a synthetic polymer. Borax, which is a white powder made up of sodium tetraborate, can react with this acetate group.
What is molecular formula of borax and boric acid?
The molecular formula for borax is Na2[B4O5(OH)4]. 8H2O and boric acid is H3BO3.
What is the formula of boric acid?
H3BO3
Boric acid/Formula
Does Borax contain a monomer?
The monomer has a formula of: Borax is sodium borate, Na3BO3. The borax actually dissolves to form boric acid, H3BO3. This boric acid-borate solution is a buffer with a pH of about 9 (basic).
What is polyvinyl alcohol with borax?
Slime – Polyvinyl Alcohol with Borax Description: This demonstration is typically performed as a hands-on activity for younger audiences but can also be used to discuss polymerization. Two clear colorless liquids are mixed and immediately form a gel with interesting physical properties.
How do you make paint with polyvinyl alcohol?
Place 40 cm 3 of the polyvinyl alcohol solution in the plastic cup. If supplied, add one drop of food colour or fluorescein dye to the solution. Stir well. Measure out 10 cm 3 of borax solution into the beaker and add this to the polyvinyl alcohol solution, stirring vigorously until gelling is complete.
What is the molecular formula for polyvinyl alcohol?
Polyvinyl alcohol PubChem CID 11199 Structure Find Similar Structures Chemical Safety Laboratory Chemical Safety Summary (LCSS Molecular Formula CH2CHOH or C2H4O Synonyms Ethenol POLYVINYL ALCOHOL VINYL ALCOHOL
How do you make slime with polyvinyl alcohol?
A solution of polyvinyl alcohol (PVA) can be made into a slime by adding borax solution, which creates cross-links between polymer chains. In this activity, some interesting properties of the slime are investigated. Students are guaranteed to enjoy the activities involved
