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.
ACIDS AND BASES Electrolytes-substances which will conduct electricity when dissolved in water. Typical electrolytes are strong acids and salt solutions; e.g., NaCl(aq), HCl(aq), etc. Nonelectrolytes-substances which do not conduct electricity in water solutions.Strong electrolytes-substances which are good conductors of electricity in water solutions.Weak electrolytes-substances which are poor conductors of electricity in water solutions.onelectrolytes-substances which do not conduct electricity in water solutions.
