Resumen de Experimentation and Group Discussion as a Means of Determining Solubility Rules
An experimental method is presented that leads to the development of solubility rules. A set of experiments is performed as a class demonstration and then discussed in groups. As a result, a classification of all the ionic species present can be made in terms of their solubility. This approach to the learning of solubility rules is significantly different from traditional methods in which students merely memorize rules. In the current method, student comprehension and involvement is increased.
