Single Idea 17483

[filed under theme 27. Natural Reality / F. Chemistry / 1. Chemistry ]

Full Idea

Macroscopic bodies of water are complex and dynamic congeries of different molecular species, in which there is a constant dissociation of individual molecules, re-association of ions, and formation, growth and disassociation of oligomers.

Clarification

'Oligomers' are chains of molecules

Gist of Idea

Water continuously changes, with new groupings of molecules

A Reaction

The point is that these activities are needed to explain the behaviour of water (such as its conductivity).


The 11 ideas from 'Chemistry'

Elements survive chemical change, and are tracked to explain direction and properties [Hendry]
Defining elements by atomic number allowed atoms of an element to have different masses [Hendry]
Generally it is nuclear charge (not nuclear mass) which determines behaviour [Hendry]
Nuclear charge (plus laws) explains electron structure and spectrum, but not vice versa [Hendry]
Maybe two kinds are the same if there is no change of entropy on isothermal mixing [Hendry]
Maybe the nature of water is macroscopic, and not in the microstructure [Hendry]
The nature of an element must survive chemical change, so it is the nucleus, not the electrons [Hendry]
Maybe water is the smallest part of it that still counts as water (which is H2O molecules) [Hendry]
Compounds can differ with the same collection of atoms, so structure matters too [Hendry]
Water continuously changes, with new groupings of molecules [Hendry]
Supervenience is simply modally robust property co-variance [Hendry]
