  Activity: Acid Base Escape Room Mark as Favorite (3 Favorites)

  In this activity, students will work collaboratively to apply their acid-base chemistry knowledge in order to “escape the room.” Students will have to apply their understanding of many different facets of acid-base chemistry, including the Arrhenius Acid-Base model, Brønsted-Lowry Acid-Base model, pH calculations, and acid-base titrations, while utilizing puzzles and ciphers to work through the escape room clues. This engaging activity is not only fun for all students but also allows for interactive and collaborative review.

  Lesson Plan: Categorizing, Calculating and Applying Concepts from Weak Acids, Weak Bases and Salts Mark as Favorite (58 Favorites)

  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.

•

  Lab: Hydrolysis of Salts Mark as Favorite (17 Favorites)

  In this lab, students will observe the hydrolysis of several salt samples. They will first predict which solutions are acidic, basic or neutral, and then discover the pH of each through the use of indicators. Students will share and compile their experimental results, as well as have an opportunity to determine the net-ionic equations for each reaction.

• 

  Lab: Acid/Base Stoichiometry Mark as Favorite (13 Favorites)

  In this lab, students experience a limiting reactant and can physically see the difference in amounts of product generated. They also see which reactant is in excess.

• 

  Lab: Acid Base Reactions Mark as Favorite (7 Favorites)

  In this lab, students will witness a reaction between an acid and base. One will be strong, and the other may be weak or strong--it's up to them to determine.
