Science Classroom Connection

We will review the properties of acids and bases, and then we will explain the meaning and importance of pH of matter. Moreover, we will elaborate upon the neutralization process between acids and bases, and briefly introduce the concept buffer as it plays a major role in chemical reactions.

We will discuss what happens to a substance such as ammonia that is dissolved in water in terms of its forward and reverse reactions and identify the conjugate acid, conjugate base, and the two conjugate acid-base pairs. Moreover, we will elaborate briefly upon the Lewis Model by defining an anhydride and give examples upon it and distinguish between those that produce an acid and those that produce a base. Furthermore, we will reinforce the characteristics or properties of acids and bases by a comparative study along with the models that we have discussed. This reinforcement will be turned in as a formative assessment.

Students will learn how to identify an acid from a base using the physical and chemical properties of acids and bases. Moreover, students will learn about the classification of solutions in terms of being acidic, basic, or neutral. Furthermore, students will briefly touch upon the Arrhenius and Bronsted Models as well as review and elaborate briefly upon the Lewis Model.

Students will review and reinforce their work on solvation and solubility from yesterday. Then we will discuss the societal issue: Acid Rain. We will examine the causes and effects of acid rain on lakes, specifically those that are vulnerable to acid rain in the State of Minnesota, and comment about the pH of rain and acid rain in general.

Students will reinforce the topic on solvation and solubility by analyzing the main concepts and ideas that we have discussed and elaborated upon in class. If time permits, students will read about one of our social issues that centers on acid rain and elaborate on its significance in our environment.
