Sheep were the basis of their wealth, and by 1850 there were more than 15 million head in Australia. Squatting was legitimized in 1836, after the British government recognized the impossibility of enforcing the original settlement restrictions.
When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution. Some substances that are made of molecules form solutions that do conduct electricity. Ammonia is such a substance.
Solids do not conduct electricity (electrons are tightly bound to ions) In aqueous solution, or when melted to a liquid, ionic compounds do conduct electricity (ions are now free to move). This is often an identifying feature of an ionic solid. Tend to be soluble in polar solvents and insoluble in nonpolar solvents.
