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.
Substances that exist in solution almost completely as ions are called strong electrolytes. Substances that do not form ions when they dissolve in water are called non-electrolytes. And example of a non-electrolyte is sugar. Sugar will readily dissolve in water but doesn't form cations and anions in solution. That is, there are no charge carriers formed.
