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.
The ability of a solution to conduct an electric current is dependent on the concentration (number) of ions in solution. The greater the concentration of ions in solution, the greater the electrical conductivity. If a solution of an acid is a a good conductor of electricity, it is called a strong acid. If such a solution is a poor conductor, it is termed a weak acid.
