1. Show the class pictures of five very different mammals, such as a cat, kangaroo, horse, rabbit, and monkey. Explain that all these animals are mammals, and that mammals constitute one class of the animal kingdom, which also includes other classes, such as reptiles, birds, and fish. Ask students what these five mammals have in common and mark their responses on a sheet of chart paper.
When ionic compounds are in a molten state or dissolved in water, forming an aqueous solution, the ions that formed the ionic compounds are able to move around freely, thus able to conduct electricity.
Ionic compounds are soluble in water because it a very polar compound. Ionic compounds are also very polar and thus very soluble. The water solvates each ion in the ionic comp â¦ ound. The negative ion of the ionic compound will be surrounded by water molecules with the hydrogen atoms closest.f an organic compound is relatively small, and has a polar end, it may become soluble in water. This depends on how long the carbon-chain is, compared to how polar the polar end of the chain is. I.e. Ethanol is polar and water soluable, while decanol is not.
