CHEMISTRY OF WATER
WAT-1Kit Contents:

1 silver 6-peg sodium ion
1 green 6-peg chloride ion
36-0.75" PVC, clear tubes (lone pairs of electrons) 24-0.75" PVC, white tubes (hydrogen atoms)
60-4mm x 1/2" cylindrical magnets Assembly instructions
Background information booklet
Lab procedure, student response form, and answer key

Each water molecule has a central 4-peg, red-oxygen atom center to which are bonded two white tubes representing the hydrogen atoms and two clear tubes to show the two pairs of nonbonding electrons of the oxygen atom. Cylindrical, very strong magnets are aligned within the four tubes so that the free ends of the two hydrogen atoms are south, while the lone electron pair ends are both north. Therefore, the hydrogen of one molecule bonds to a lone pair of electrons on another water molecule.

The south ends of the magnets placed in the clear tubes on the sodium ion will attract the water's lone pairs, and the north ends of the chloride ion will bond to the hydrogens of the water.

Science classes from 5th grade through high school will benefit from investigating the properties of this most ubiquitous substance. The kit demonstrates hydrogen bonding, molecular shape, bond and molecular polarity, expansion of water on cooling, solvation of a salt, surface tension, tension and cohesion, transpiration in plants, colligative properties of water, etc.
