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.
Strong and Weak Electrolytes. Strong Electrolytes conduct current very efficiently. Completely ionized or dissociate when dissolved in water (single arrow). a. Soluble Ionic compounds. b. Strong acids (HNO. c. Strong bases (KOH and NaOH). ***covalent substances ionize....ionic substances dissociate. Weak electrolytes conduct only a small current.
