• Acid & Base Theories, Concentration | High School

### Access is an AACT member benefit. Lesson Plan: Calculating pH, A Look at Logarithms

In this lesson, students will be introduced to a base-10 logarithmic scale and use it to calculate pH from hydrogen ion concentration. Often students are able to calculate pH by pushing the correct buttons on their calculators, but they don’t understand what the values mean. This lesson attempts to bridge that gap using a guided inquiry model.

### Access is an AACT member benefit. Lesson Plan: Categorizing, Calculating and Applying Concepts from Weak Acids, Weak Bases and Salts

In this lesson students will write dissociation reactions to make connections between conjugate acid-base pairs. They will use beaker diagrams in a cooperative group activity to better understand why the pH calculation for a weak acid/base is not the same for a strong acid/base. Finally, students will apply these concepts in a lab in which they will identify several unknown, clear, colorless solutions using factors such as pH, conductivity and reactivity. The activities in this lesson can be used in sequence or as standalone activities.
