1 – 15 of 15 Classroom Resources

  • pH, Net Ionic Equation, Indicators, Strong vs Weak, Salts | High School

    Lab: Hydrolysis of Salts

    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.

  • Interdisciplinary, pH, Indicators | High School, Middle School

    Lab: Exhaling Acid

    In this lab students will observe how increased carbon dioxide levels lead to a build-up of acidic conditions.

  • pH, Indicators | High School

    Lab: Exploring the Properties of Acids and Bases

    In this lab, students will rotate through five stations. They will explore the properties of many household substances and discover a few properties of acids and bases.

  • Acid Base Reactions, Stoichiometry, Percent Composition, Titrations, Indicators | High School

    Lab: The Egg-straordinary Issue

    In this lab students will determine the percent composition of calcium carbonate contained in an eggshell by using a back titration in order to address a farmer’s concerns about his hen’s fragile eggs. Two versions of the student lab are included, a scripted version, and an inquiry version.

  • Concentration, pH, Molarity, Titrations, Indicators | High School

    Demonstration: How to Perform a Titration

    In this demonstration, the teacher will show how a titration is set-up and performed. Also, the teacher will utilize different indicators to show how they work and why they are necessary. At the end of the demonstration, the teacher will also explain how to calculate the molarity of the unknown substance.

  • Identifying an Unknown, Indicators | High School, Middle School

    Lab: Indicators of Acids and Bases

    In this lab, students will use various indicators to identify unknown (clear) solutions as acidic, basic, or neutral.

  • pH, Indicators | High School, Middle School

    Lab: Cellular Respiration and pH

    In this lab, students learn how a pH indicator can be used to detect the presence of CO2 when they exhale.

  • pH, Titrations, Indicators, Strong vs Weak | High School

    Lab: Titration Curves

    In this lab, students graphically observe a plot of micro acid/base titrations and determine the equivalence point of each plotted curve.

  • pH, Titrations, Indicators, Strong vs Weak | High School

    Lab: Titration

    In this lab, students will learn the difference between strong, weak, and concentrated acids by carrying out various titrations.

  • Indicators | Middle School, Elementary School, High School

    Demonstration: Secret Message

    In this lesson, students will observe a hidden message while understanding simple acid/base chemistry and indicators.

  • pH, Indicators | Middle School, High School

    Lab: Detecting pH of Commonly Used Acids and Bases

    In this lab, students will use their knowledge of acids and bases to determine the acidity and basicity of every day items by measuring pH using several different methods for determination. Indications of pH may be determined using red & blue litmus paper, pH strips, and pH probes or pH meters.

  • Titrations, Indicators, Strong vs Weak | High School

    Lab: Meet The Indicators

    In this lab, students will use their background with titrations to see how different indicators change colors at different pH's.

  • Acid Base Reactions, Indicators | Middle School, Elementary School, High School

    Demonstration: Another Secret Message

    In this demonstration, students will observe a hidden message while understanding simple acid/base chemistry and indicators.

  • Solubility, Acid Base Reactions, Intermolecular Forces, Titrations, Indicators | High School

    Lab: Alka-Seltzer & Gas Solubility

    In this lab, students will use a reaction to investigate temperature and the solubility of carbon dioxide and will use a neutralization reaction and an indicator to verify the amount of carbon dioxide produced at each temperature.

  • Indicators, Le Châtelier's Principle | High School

    Demonstration: Milk of Magnesia Magic

    In this demonstration, students will observe a color change in a milk of magnesia solution as vinegar is added.
