Classroom Resources: Solutions
1 – 12 of 12 Classroom Resources
Precipitate, Reaction Rate, Reduction, Redox Reaction, Chemical Change, Oxidation, Solubility Rules | High School
In this lab, students investigate the use of milk of magnesia poultice to remove copper stains on masonry in copper architecture. They use chalk as the model for masonry, copper(II) chloride solution as a model for soluble copper and a freshly prepared slurry of copper phosphate as a model for a hard stain of copper on masonry. Through a series of investigations students have the opportunity to connect chemistry topics with real-world applications, such as environmental hazards, engineering practices of copper architecture, corrosion control, and structural protection.
Precipitate, Net Ionic Equation, Classification of Reactions, Solubility Rules | High School
In this lesson students will use solubility rules to predict whether the product of a double displacement or metathesis reaction will produce a precipitate. Students will then investigate a series of reactions to verify solubility rules. Finally students will determine the identity of unknown solutions based on experimental evidence.
Precipitate, Electron Configuration, Valence Electrons, Balancing Equations, Classification of Reactions, Solubility Rules, Electrons | High School
In this lesson students will complete a series of double replacement reactions to form precipitates. The precipitates will be used as a pigment to create paint.
Precipitate, Balancing Equations, Solubility Rules | High School
In this animation, students will witness a precipitate reaction on the particulate level to understand why a net ionic equation represents what happens in these reaction types. An example of diluting a soluble solid, mixing two aqueous reactants that yield aqueous products, and mixing two aqueous reactants that yield a precipitate are part of this animation. **This video has no audio**
Observations, Separating Mixtures, Solubility, Concentration, Precipitate, Identifying an Unknown, Molarity, Net Ionic Equation, Balancing Equations, Percent Yield, Stoichiometry, Limiting Reactant, Mole Concept, Dimensional Analysis, Graphing | High School
In this lab, students use molarity concepts to review limiting reactant concepts mathematically, conceptually, and graphically. They can then carry out a follow up investigation to identify an unknown using concepts learned in the first investigation.
Concentration, Precipitate, Net Ionic Equation, Balancing Equations, Stoichiometry, Limiting Reactant, Mole Concept, Dimensional Analysis | High School
In this lab, students will measure how much carbon dioxide they exhale by reacting their exhaled breath with lime water (calcium hydroxide).
Precipitate, Conductivity, Classification of Reactions, Chemical Change | High School
In this demonstration, students will observe a decomposition reaction that triggers a precipitate reaction that prevents a solution from conducting electricity.
Solubility, Chemical Change, Precipitate, Net Ionic Equation, Balancing Equations, Chemical Change, Solubility Rules | High School
In this lab, students will mix ionic solutions to determine what combinations form precipitates.
Solubility, Covalent Bonding, Precipitate, Ionic Bonding, Molecular Structure, Solute & Solvent, Saturated/Unsaturated/Supersaturated | High School, Middle School
In this lab, students create a snow globe by taking advantage of benzoic acid’s solubility properties in hot water.
Solubility, Precipitate, Solute & Solvent, Saturated/Unsaturated/Supersaturated | High School, Elementary School, Middle School
In this lab, students will create a supersaturated solution by dissolving borax in boiling water. They will create a snowflake using pipe cleaner to suspend in the solution, which will serve as a nucleation site for crystallization as the solution cools and remains undistributed overnight. This lab gives students an opportunity to experience the exciting crystallization process and become more familiar with an engaging chemistry spectacle!
Naming Compounds, Molecular Formula, Precipitate, Ionic Bonding, Ions | Middle School
In this activity, students are assigned an ion and form bonds with their classmates, recording the formula and name of the compound they created.
Chemical Change, Precipitate, Balancing Equations, Chemical Change, Chemistry Basics, Solubility Rules, Reactions & Stoichiometry | High School, Middle School
In this lab, students use solubility rules to predict which chemical reactions will produce precipitates.
