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.
An electrolyte solution conducts electricity because of the movement of ions in the solution. The larger the concentration of ions, the better the solution conducts. Weak electrolytes, such as HgCl2, conduct badly because they produce very few ions when dissolved and exist mainly in the form of molecules.
