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.
Citric acid does not produce electricity by itself. Rather, this weak acid turns into an electrolyte -- an electrically conductive substance -- when it's dissolved in fluid. The charged ions of the electrolyte allow electricity to travel through the fluid.
