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.
) or a non-electrolyte (e.g. sugar, alcohol, oil) will affect the conductivity of water because the concentration of ions in solution will be different in each case. Strong electrolytes form ions easily, weak electrolytes do not form ions easily and non-electrolytes do not form ions in solution. Investigating solutions.lectrolytes, ionisation and conductivity. You have learnt that water is a polar molecule and that it can dissolve ionic substances in water. When ions are present in water, the water is able to conduct electricity. The solution is known as an electrolyte.
